    ABSTRACT: A ternary photocatalyst TiO2-Au-CdS based on three-dimensionally ordered macroporous TiO2 (3DOM TiO2) was successfully prepared to enhance the light absorption, extend the light responsive region, reduce the recombination rate of charge carriers and promote the efficiency of water splitting H2 evolution ultimately. The obtained 3DOM TiO2-Au-CdS powder has a pure anatase phase of TiO2 and greenockite structured CdS according to the XRD results and TEM analysis. Au nanoparticles (AuNPs) and CdS were evenly distributed in the 3DOM structure which enhances H2-generation rate under visible light by improving light harvesting and utilizing its mass transfer facilitation. As a result, the hydrogen generation rate (1.81 mmol h−1 g−1) using 3DOM TiO2-Au-CdS photocatalyst under visible light irradiation was 13-fold higher than the binary 3DOM TiO2-CdS reference photocatalyst. Under ultraviolet-visible light, the photogenerated electrons in TiO2 would be transferred to recombine with the holes of CdS and under visible light, electrons would move to the conduction band (CB) of TiO2 from CdS via AuNPs. The two different types of internal electron-transfer process in the ternary photocatalyst under ultraviolet and visible light were proposed respectively and both would efficiently reduce the recombination rate of photogenerated electrons and holes thus stimulate H2 evolution rate. The present work demonstrated an excellent example of the synergistic effect of the light absorption enhancement by 3DOM structure, the photosensitizing and electron reservoir effect of AuNPs and the reduction of recombination rate of charge carriers by CdS to highly promote the photocatalytic activity in water splitting reaction.

    ABSTRACT: Two dimensional (2D) ZnO nanosheets are ideal system for dimensionally confined transport phenomenon investigation owing to specific surface atomic configuration. Therefore, 2D ZnO porous nanosheets with single-crystal nature and {0001} polar facets, likely display some specific physicochem-ical properties. In this work, for the first time, 2D ZnO mesoporous single-crystal nanosheets (ZnO-MSN) with {0001} polar facets have been designed and prepared via an intriguing colloidal templating approach through controlling the infiltration speed for the suspension of EG-capped ZnO nanoparticles and polymer colloids. The EG-capped ZnO nanoparticles are very helpful for single-crystal nanosheet formation, while the polymer colloids play dual roles on the mesoporosity generation and {0001} polar facets formation within the mesopores. Such special 2D structure not only accelerates the hole-electron separation and the electron transportation owing to the single-crystal nature, but also enhances the selective adsorption of organic molecules owing to the porous structure and the exposed {0001} polar facets with more O-termination (000-1) surfaces: the 2D ZnO-MSN shows highly selective adsorption and significantly higher photodegradation for positively charged rhodamine B than those for negatively charged methyl orange and neutral phenol, comparing with ZnO nanoparticles (ZnO-NP) and ZnO commercial nanoparticles (ZnO-CNP) with high surface areas. This work may shed some light on better understanding the synthesis of 2D porous single-crystal nanosheet with exposed polar surfaces and photocatalytic mechanism of nanostructured semiconductors in a mixed organic molecules system.

    ABSTRACT: Structure-forming processes leading to biominerals are well worth learning in pursuit of new synthetic techniques. Strategies that attempt to mimic nature in vitro cannot replace an entire complex natural organism, requiring ingenuity beyond chemists′ hands. A “bioprocess-inspired synthesis” is demonstrated for fabrication of N-doped TiO2 materials at ambient temperature by direct implantation of precursor into living mussels. The amorphous precursor transforms into N-doped anatase TiO2 with a hierarchical nanostructure. Synthetic TiO2 exhibits high phase stability and enhanced visible-light photocatalytic activity as a result of modifications to its band gap during in vivo mineralization. Intracellular proteins were found to be involved in TiO2 mineralization. Our findings may inspire material production by new synthetic techniques, especially under environmentally benign conditions.

    ABSTRACT: Engineering hierarchical structures of electrode materials is a powerful strategy for optimizing the electrochemical performance of an anode material for lithium-ion batteries (LIBs). Herein, we report the fabrication of hierarchical TiO2/C nanocomposite monoliths by mediated mineralization and carbonization using bacterial cellulose (BC) as a scaffolding template as well as a carbon source. TiO2/C has a robust scaffolding architecture, a mesopore-macropore network and TiO2-C heterostructure. TiO2/C-500, obtained by calcination at 500 °C in nitrogen, contains anatase TiO2-C heterostructure with a specific surface area of 66.5 m2 g-1. When evaluated as an anode material at 0.5 C, TiO2/C-500 exhibits high and reversible lithium storage capacity of 188 mA h g-1, excellent initial capacity of 283 mA h g-1, long cycle life with 94 % coulombic efficiency preserved after 200 cycles, and very low charge transfer resistance. The superior electrochemical performance of TiO2/C-500 is attributed to the synergistic effect of high electrical conductivity, anatase TiO2-C heterostructure, mesopore-macropore network and robust scaffolding architecture. The current material strategy affords a general approach for the design of complex inorganic nanocomposites with structural stability, and tailorable and interconnected hierarchical porosity that may lead to next generation of electrochemical supercapacitors with high energy efficiency and superior power density.

    ABSTRACT: Tunable macro–mesoporous ZnO (M/m-ZnO) nanostructures with a wurtzite hexagonal structure have been successfully synthesized using polymer colloids as a hard template and 20–40 nm ZnO nanoparticles as a precursor via controlling the ratios of colloids and ZnO nanoparticles. The as-prepared macro–mesoporous ZnO nanostructures are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) techniques. Gas sensing performance is carried out for ethanol and acetone at different temperatures and concentrations. The gas sensing results show that the tunable M/m-ZnO nanostructures exhibit excellent gas sensing performances because the hierarchical macro–mesopores provide a large contacting surface area for electrons, oxygen and target gas molecules, offer smooth transport channels for target gas diffusion and finally enhance the gas molecular diffusion kinetics. The M/m-ZnO-600 nm demonstrates the best performance for ethanol and acetone detection. In addition, the sensor based on M/m-ZnO-600 nm gives obvious tendencious selectivity and a good repeatability and long-term stability to acetone at the optimum temperature of 300 °C. This work suggests that the macro–mesoporous ZnO is a potential material for advanced gas sensing.

    ABSTRACT: Light harvesting enhancement by slow photons in photonic crystal catalysts or dye-sensitized solar cells is a promising approach for increasing the efficiency of photoreactions. This structural effect is exploited in inverse opal TiO2 photocatalysts by tuning the red edge of the photonic band gap to the TiO2 electronic excitation band edge. In spite of many experimental demonstrations, the slow photon effect is not fully understood yet. In particular, observed enhancement by tuning the blue edge has remained unexplained. Based on rigorous couple wave analysis simulations, we quantify light harvesting enhancement in terms of absorption increase at a specific wavelength (monochromatic UV illumination) or photocurrent increase (solar light illumination), with respect to homogeneous flat slab of equivalent material thickness. We show that the commonly accepted explanation relying on light intensity confinement in high (low) dielectric constant regions at the red (blue) edge is challenged in the case of TiO2 inverse opals because of the sub-wavelength size of the material skeleton. The reason why slow photons at the blue edge are also able to enhance light harvesting is the loose confinement of the field, which leads to significant resonantly enhanced field intensity overlap with the skeleton in both red and blue edge tuning cases, yet with different intensity patterns.

    ABSTRACT: Bicontinuous hierarchically porous Mn2O3 single crystals (BHP-Mn2O3-SCs) with uniform parallelepiped geometry and tunable sizes have been synthesized and used as anode materials for lithium-ion batteries (LIBs). The monodispersed BHP-Mn2O3-SCs exhibit high specific surface area and three dimensional interconnected bimodal mesoporosity throughout the entire crystal. Such hierarchical interpenetrating porous framework can not only provide a large number of active sites for Li ion insertion, but also good conductivity and short diffusion length for Li ions, leading to a high lithium storage capacity and enhanced rate capability. Furthermore, owing to their specific porosity, these BHP-Mn2O3-SCs as anode materials can accommodate the volume expansion/contraction that occurs with lithium insertion/extraction during discharge/charge processes, resulting in their good cycling performance. Our synthesized BHP-Mn2O3-SCs with a size of ~700 nm display the best electrochemical performance, with a large reversible capacity (845 mA h g-1 at 100 mA g-1 after 50 cycles), high coulombic efficiency (>95%), excellent cycling stability and superior rate capability (410 mA h g-1 at 1 Ag-1). These values are among the highest reported for Mn2O3-based bulk solids and nanostructures. Also, electrochemical impedance spectroscopy study demonstrates that the BHP-Mn2O3-SCs are suitable for charge transfer at the electrode/electrolyte interface.

    ABSTRACT: Novel 3DOM BiVO 4 /TiO 2 nanocomposites with intimate contact were for the first time synthesized by a hydrothermal method in order to elucidate their visible-light-driven photocatalytic performances. BiVO 4 nanoparticles and 3DOM TiO 2 inverse opal were fabricated respectively. These materials were characterized by XRD, XPS, SEM, TEM, N 2 adsorption–desorption and UV-vis diffuse (UV-vis) and photoluminescence spectroscopies. As references for comparison, a physical mixture of BiVO 4 nanoparticles and 3DOM TiO 2 inverse opal powder (0.08 : 1), and a BiVO 4 /P25 TiO 2 (0.08 : 1) nanocomposite made also by the hydrothermal method were prepared. The photocatalytic performance of all the prepared materials was evaluated by the degradation of rhodamine B (RhB) as a model pollutant molecule under visible light irradiation. The highly ordered 3D macroporous inverse opal structure can provide more active surface areas and increased mass transfer because of its highly accessible 3D porosity. The results show that 3DOM BiVO 4 /TiO 2 nanocomposites possess a highly prolonged lifetime and increased separation of visible light generated charges and extraordinarily high photocatalytic activity. Owing to the intimate contact between BiVO 4 and large surface area 3DOM TiO 2 , the photogenerated high energy charges can be easily transferred from BiVO 4 to the 3DOM TiO 2 support. BiVO 4 nanoparticles in the 3DOM TiO 2 inverse opal structure act thus as a sensitizer to absorb visible light and to transfer efficiently high energy electrons to TiO 2 to ensure long lifetime of the photogenerated charges and keep them well separated, owing to the direct bandgap of BiVO 4 of 2.4 eV, favourably positioned band edges, very low recombination rate of electron–hole pairs and stability when coupled with photocatalysts, explaining the extraordinarily high photocatalytic performance of 3DOM BiVO 4 /TiO 2 nanocomposites. It is found that larger the amount of BiVO 4 in the nanocomposite, longer the duration of photogenerated charge separation and higher the photocatalytic activity. This work can shed light on the development of novel visible light responsive nanomaterials for efficient solar energy utilisation by the intimate combination of an inorganic light sensitizing nanoparticle with an inverse opal structure with high diffusion efficiency and high accessible surface area.

    ABSTRACT: Hierarchical nanorods chains-constructed TiO 2 hollow microspheres (HNC-TiO 2-HMSs) have been designed and prepared through a facile one-pot fluorine-free solvothermal alcoholysis route using TiCl 4 and isopropanol reaction system. Owing to the assembly of radially oriented nanorods chains leading to the formation of the shell of the hollow spheres, a large series of straight channels along nanorods chains are formed. Such highly porous hollow microspheres with hollow cavity, straight nanorods chains and straight nanochannels are highly desirable for Li ions batteries because such structure can easily store the electrolyte, facilitate the charge diffusion and Li + insertion and buffer the volume change during the Li + insertion/extraction process. One of the key innovation of the present work is the fine tuning of water amount released from the esterification of alcohol to induce in a well controlled hydrolysis of TiCl 4 and engineer precisely HNC-TiO 2-HMSs formation. Most importantly, the released Cl À ions direct the nanorods growing along (001) crystal plane and self-assembling along the radial direction

    ABSTRACT: Inspired by the structure-forming process of biominerals, scientists have been successful in synthesizing materials with elegant structures by using organic matrices as templates. However, there are still issues relating to the exquisiteness and complexity of natural organic matrices in living organisms which have kept their activities out of chemists' control, in particular the functional properties of such materials. Here we employ natural assorted proteins, which are derived from the extrapallial fluid in living mussels, to synthesize hierarchically porous nitrogen-doped TiO2 in a single process. The silk-like organic residues in the powders clearly show that the proteins act to segment the space for TiO2 nucleation. We also demonstrate phase control over the material, with the ability to synthesize pure anatase. The synthesized TiO2 materials show a significant improvement in visible-light photocatalytic activity for both the degradation of organic pollutants and hydrogen production. The degradation of RhB could be almost completed in just 20 min. The visible-light photocatalytic activities vary with the concentrations of EPF proteins, and the optimal concentration of protein was found to be 600 μg mL-1. The present work highlights its potential application as a natural organic matrix in producing advanced materials with optimized functional properties. This journal is

    ABSTRACT: This chapter presents an overview of the synthesis strategies based on the sol-gel process for the preparation of multimodal porous networks of hierarchically structured functional materials and a brief introduction to their applications as photocatalysts, scaffold templates, and catalyst supports. Until now, many successful examples have been reported for the preparation of hierarchically porous materials by combining a single templating method with a supplementary chemical or physical method. The chapter provides an introduction to the synthesis strategies for the preparation of hierarchically porous materials using the dual and multiple micellar templates in hierarchically porous material synthesis. It reviews the features and history of self-formation phenomenon to target hierarchically structured porous materials based on metal alkoxides. The chapter also reviews the effects of general synthesis conditions on the self-formation phenomenon, including metal alkoxide, surfactant, solvent, pH values, and hydrothermal synthesis.

    ABSTRACT: Extreme conditions such as high temperature and/or pressure are usually required for transformation of amorphous silica to crystalline polymorphs. In this article, we presented our results that amorphous silica can be deposited on bacterial surface and transformed to cristobalite at a relatively low temperature and ambient pressure. The phase transformation of amorphous silica to cristobalite under thermal treatment was investigated by a variety of methods including X-ray diffraction, electron microscopy, and Fourier transform infrared spectroscopy. Results show that amorphous silica on bacterial cell surface exhibits a direct phase transformation to cristobalite structure at a relatively low temperature (800oC). Surface charge of bacterial cells does not affect the phase transformation. Three Gram negative bacteria and three Gram positive bacteria have been tested in the present study. All of these bacteria have been found to facilitate phase transition of amorphous silica into cristobalite. The observation of induced amorphous silica transformation on bacterial surface to cristobalite highlights the use of bacteria in the synthesis and the structure control of silica minerals.

    ABSTRACT: Hierarchically structured porous anatase TiO2 spheres have been fabricated by a facile chemical route. The TiO2 spheres are constructed by interconnected nanorods and possess a three-dimensional (3D) interpenetrating porous framework. When evaluated as an electrode material in lithium half-cells, such hierarchically porous TiO2 nanostructures exhibit high lithium storage capacity (225 mA h g−1 at 0.5 C), excellent rate performance (141 mA h g−1 at 5 C), and long cycle life (an initial Li+ storage capacity of 187 mA h g−1 at 1 C and a capacity retention of ca. 95% after 100 cycles). The improved electrochemical properties of TiO2 spheres can be attributed to the synergetic effects of their unique hierarchical structure, high surface area, large and opened pore structure and interconnected 3D network. These unique structural characteristics effectively improve the mass transfer capability of electrolyte, reduce the Li ions diffusion paths and increase the electronic conduction as well as structural stability.

    ABSTRACT: A hierarchical nanosheet-constructed yolk-shell TiO2 (NYTiO2) porous microsphere is synthesized through a well-designed, one-pot, template-free solvothermal alcoholysis process using tetraethylenepentamine (TEPA) as the structure directing reagent. Such a yolk-shell structure with a highly porous shell and dense mesoporous core is quite advantageous as an anode material for lithium ion batteries (LIBs). The outer, 2D nanosheet-based porous (15 nm) shell and the nanocrystal-based inner mesoporous (3 nm) core provide a stable, porous framework, effective grain boundaries and a short diffusion pathway for Li(+) and electron transport, facilitating lithium insertion/extraction. The voids between the core and the shell can not only store the electrolyte due to capillary and facilitate charge transfer across the electrode/electrolyte interface but also buffer the volume change during the Li(+) insertion/extraction. As a result, NYTiO2 demonstrates excellent Li(+) capacity with outstanding cycle performance and superior rate capability at different rates for >700 cycles, retaining a 225 mA h g(-1) reversible capacity after 100 cycles at 1 C. In particular, the reversible capacity can still be maintained at 113 mA h g(-1) after 100 cycles at 10 C. We also observe the formation of homogeneously distributed 5-10 nm Li2Ti2O4 nanocrystallites on the surface of the nanosheets during the discharge-charge process. The synergy of the yolk-shell structure with dual mesopores in the shell and core and the Li2Ti2O4 nanocrystallites endow the hierarchical NYTiO2 with high reversible capacity, excellent rate capability and outstanding cycle performance.

    ABSTRACT: Hierarchically structured porous TiO2-B spheres have been synthesized via a hydrothermal process using amorphous titania/oleylamine composites as a self-sacrificing template. The TiO2-B spheres are constructed by interconnected nanotubes and possess a high specific surface area of 295 m(2) g(-1). When evaluated as an anode material in lithium-half cells, the as-obtained TiO2-B material exhibits high and reversible lithium storage capacity of 270 mA h g(-1) at 1 C (340 mA g(-1)), excellent rate capability of 221 mA h g(-1) at 10 C, and long cycle life with over 70% capacity retention after 1000 cycles at 10 C. The superior electrochemical performance of TiO2-B material strongly correlates to the synergetic superiorities with a combination of TiO2-B polymorph, hierarchically porous structure, interconnected nanotubes and spherical morphology. Post-mortem structural analyses reveal some discrete cubic LiTiO2 nanodots formed on the outer surfaces of TiO2-B nanotubes, which might account for the slight capacity loss upon prolonged electrochemical cycling.

    ABSTRACT: Hollow Cu2O microspheres (0.7 to 4 μm in diameter) with two active {111} and {110} facets have been prepared in water/ethylene glycol solution via a fast hydrothermal route in only 1 h. Due to the dangling “Cu” atoms in the highly active {111} and {110} facets, the microspheres demonstrate preferential selective adsorption and photodegradation for negatively charged methyl orange (MO), comparing to cationic rhodamine B (RhB) and neutral phenol. The 0.7 μm hollow Cu2O microspheres demonstrate the best adsorption capacity and photodegradation performance for MO removal: 49% MO can be adsorbed in 60 min and 99.8% MO can be fully removed under visible light illumination in 80 min, owing to the two active {110} and {111} facets and hollow structure. To exactly evaluate the photocatalytic efficiency, a new methodology is proposed by deducting the adsorption effect. The results show that in spite of 99.2% MO is removed from the solution under visible light illumination in 60 min, 14% MO is still adsorbed on the catalyst, which can be totally removed under further 20 min illumination. Our synthesis strategy presents a new opportunity for the preparation of hollow structures with high active facets. And the proposed accurate evaluation methodology may be extended to other photocatalysts with high adsorption capability for organic pollutants.

    ABSTRACT: Living organisms can produce elegant structures with unique functions and properties through biological processes. Various proteins are involved in these processes. Inspired by structure formation of mollusc shells, a single multifunctional recombinant protein ChiCaSifi was designed on the basis of mineralization proteins for regulating CaCO3 mineralization in a simple and direct manner. The ChiCaSifi contains functional domains of chitin binding protein (Chi), calcium binding protein (Ca), and silk fibroin (Sifi). Therefore, ChiCaSifi can have multiple roles in directing CaCO3 mineralization. Overexpression and purification of ChiCaSifi were achieved. Activities of ChiCaSifi were examined on binding to calcium and chitin. Influences of ChiCaSifi were proved on regulating the phase formation of CaCO3 crystals on chitin surface. Structural changes of ChiCaSifi were evidenced and related to its functions on mineralization. These observations indicate that rational designed proteins with functional domains from mineralization proteins can be effective tools in materials synthesis. The present study may not only provide insight into the formation of natural biomaterials, but also open a new avenue in the design and synthesis of novel organic/inorganic composite materials.

    ABSTRACT: Taking lessons from the structure-forming process of biominerals in animals and plants, one can find tremendous inspirations and ideas for developing advanced synthesis techniques, which is called bio-process inspired synthesis. Bone, as a typical representative of biominerals, is constituted of mineralized collagen fibrils, which are formed under the functions of non-collagenous proteins (NCPs). Intrafibrillar mineralization is the consequence of a synergy among several NCPs. In the present study, we have designed a multi-functional protein, named (MBP)–BSP–HAP, based on bone sialoprotein (BSP) and hydroxyapatite binding protein (HAP), to mimic the intrafibrillar mineralization process in vitro. The three functional domains of (MBP)–BSP–HAP provide the artificial protein with multiple designated functions for intrafibrillar mineralization including binding calcium ions, binding collagen, and binding hydroxyapatite. Platelet-like hydroxyapatite crystals periodically arranged inside the collagen fibrils have been achieved under the function of (MBP)–BSP–HAP. The mechanism of intrafibrillar mineralization directed by the multi-functional protein was proposed. This work may not only shed light on bio-process inspired approaches for more economic and efficient biomimetic synthesis, but also be helpful in understanding the natural process of bone formation for bone regeneration and tissue repair.

    ABSTRACT: Mesoporous oxides TiO2 and ZrO2, synthesized by surfactant templating via a neutral C13(EO)6–Zr(OC3H7)4 assembly pathway, and ceria-modified TiO2 and ZrO2, prepared by a deposition–precipitation (DP) method, featuring high surface areas and uniform pore size distributions were used as supports for gold catalysts. The supported gold catalysts were assessed for the catalytic abatement of air pollutants, i.e., CO, CH3OH, and (CH3)2O. The gold was supported on the mesoporous oxides by a DP method. The supports and catalysts were characterized by powder X-ray diffraction, high-resolution transmission electron microscopy, N2 adsorption–desorption analysis, and temperature-programmed reduction technique. A high degree of synergistic interaction between ceria and mesoporous ZrO2 and TiO2 as well as a positive modification of the structural and catalytic properties by ceria was observed. The ceria additive interacts with the mesoporous oxides and induces a strong effect on the reducibility of the supports. The catalytic behavior of the catalysts was discussed to determine the role of the ceria modifying additive and possible interaction between the gold nanoparticles and ceria-mesoporous oxide supports. The gold catalysts supported on ceria-modified mesoporous ZrO2 displayed superior catalytic activity (∼100% conversion of CO at 10 °C and CH3OH at 60 °C). The high catalytic activity can be attributed to the ability of the support to assist oxygen vacancies formation. The studies indicate that the ceria-modified mesoporous oxide supports have potential as supports for gold-based catalysts.
