Article
Zinc metal is mainly produced by a hydrometallurgical process, in which zinc electrolyte is recirculated, and impurities especially halides are accumulated then, which have dreadful impacts on the process and product. Until now numerous efforts have been made to remove halides from the electrolyte, but none of them are fully satisfying, and it is s...
Article
For industries around the world, the hydrometallurgical roast–leach–electrowin process is the most common means of producing zinc metal. Dechlorination from the highly-concentrated zinc sulfate electrolyte is of vital importance to the zinc industry. In a recently published work, we innovatively employed diffusion dialysis (DD) to selectively remov...
Article
Nanobarcodes with Morse code patterns are fabricated by a programmed electrochemical deposition process. These bimetallic nanobarcodes are stable and easy to decode using optical or electrical devices. Their discretionally patterned codes offer mass memory capacity for information carriers. They show promising features as probe molecules' carriers...
Article
As one of the most successful cathode materials, LiNi1-y-zMnyCozO2 (NMC) has become the preferred choice for automotive lithium-ion batteries (LIBs). Currently, its lithium source, LiOH, is not based on primary lithium salts and the route is unsustainable due to the large resource losses and high carbon footprint. In this study, a desirable alterna...
Article
Interests on lithium extraction from the Chinese salt-lake brines have regained momentum due to the growing demand of lithium for application in electric vehicles. Characterized by a high Mg²⁺/Li⁺ ratio (MLR), the Chinese salt-lake brine has troubled scientists and engineers for decades. Recent progress has shown significant advantages of membrane...
Article
Optically pure amino alcohols are widely used as the essential building blocks for catalysts and auxiliaries in asymmetric synthesis, especially in pharmaceuticals. The catalytic hydrogenation has been regarded as the most effective route to produce chiral amino alcohols, but it is still unsatisfactory, which is mainly manifested in the involvement...
Article
Aluminum electrode foils are the most essential components inside electrolytic capacitors, which are widely used in diverse electronic systems. The production involves the usage of various chemicals, and it generates a huge amount of exhausted bath solution consisting of highly-concentrated ammonium adipate and trace Cl⁻ impurity. The loss of these...
Article
A series of polybenzimidazole copolymers with varied content of pendant amino groups have been synthesized by condensation polymerization of 4,4'-dicarboxydiphenyl ether (DCDPE), 5-aminoisophthalic acid (APTA) and 3,3’-diaminobenzidine (DAB) in polyphosphoric acid at 190 °C for 20 h. The resulting copolymers undergo post-sulfonatation in fuming sul...
Article
Abstract Currently nanofiltration predominates the membrane application of dye desalting and purification, and it is very effective to produce low-salt dye from raw dye with high inorganic salt impurities. However it is difficult and costly to produce dye products with ultralow impurities, because the desalting performance decreases proportionally...
Article
Well defined gold embedded maghemite hybrid nanowires are synthesized, and their structures are fully characterized. They are composed of porous γ-Fe2O3 shells and tiny embedment of gold nanoparticles (3-10 nm), which is novel and very different from the conventional "surface decoration" configuration. These hybrid nanowires are produced by dealloy...

Ultra-high-basicity polyaluminum, an important aluminum industrial product, is manufactured by the oxidation of metallic Al with acids. The process is not economically and chemically efficient because the aluminum atoms were reduced first from alumina to aluminum metal, and then oxidized again to get the polyaluminum. In this work, an integrated sy...
Article
Reduced graphene oxide (rGO) and NiO composites were prepared with an environmentally friendly method, in which hydrogen gas was employed as the reducing agent to convert reduced graphene oxides. Our study indicates that the success of this new approach is because NiO not only is an additive of the composites but also acts as a catalyst to facilita...
Article
Novel Au-decorated Te hybrids with a tripod-shaped planar microstructure were prepared through a two-step hydrothermal process: the synthesis of Te single crystals and the subsequent self-sacrificial reaction of Te template with HAuCl4. Based on the influences of reaction temperature and solvent compositions on the as-obtained microstructures, a pl...
Article
Noble metal Pd and Pt catalysts with a wide range of surface wettability were fabricated through an electrochemical approach and were characterized with scanning electron microscopy, energy dispersive X-ray spectroscopy, transmission electron microscopy and atomic force microscopy. The importance of surface wettability of solid catalysts in multiph...
Article
An integrated electrolysis system was built to synthesize polyaluminum chloride with ultra high-basicity and even pure Al13. The system converts AlCl3 solution from aluminum electrode foil industry waste to Al13 chloride directly with reasonable cost, typically $1.09 per kilogram as Al2(OH)5Cl·2H2O at 25 °C. Electrolyte temperature and current dens...
Article
This study developed a facile, one-pot chemical reduction method for fabricating nickel oxide (NiO) and reduced graphene oxide (rGO) composite materials. Electrochemical measurements illustrate that the NiO/rGO composite electrode with a weight ratio of 6 : 4 yields a maximum specific capacitance of 461 F g(-1) and a high energy density of 36.0 Wh...
Article
This study develops a simple, rapid electrochemical approach for preparing dendrite-shaped Ag nanomaterials, which are well known as effective SERS substrates. In addition to yielding silver that exhibits a strong enhancement in SERS measurements when tested with 2,2′-dithiodipyridine and ethylenethiourea, this new fabrication method does not requi...
Article
Carbon-coated Fe3O4 nanospindles are synthesized by partial reduction of monodispersed hematite nanospindles with carbon coatings, and investigated with scanning electron microscopy, transmission electron microscopy, X-ray diffraction, and electrochemical experiments. The Fe3O4C nanospindles show high reversible capacity (∼745 mA h g−1 at C/5 and ∼...
Article
Nanocrystalline porous tin dioxide (SnO2) materials have been obtained employing room temperature ionic liquids (1-hexadecyl-3-methylimidazolium bromide, C16MimBr) as a template via a green sol−gel method at ambient temperature followed by a suitable thermal treatment. These materials have been thoroughly characterized by X-ray diffraction (XRD), t...
Article
A new approach to synthesize tin nanoparticles encapsulated elastic hollow carbon spheres (TNHC) with uniform size for high-performance anode material in lithium-ion batteries was presented. It is found that these spheres have uniform size and shell thickness of 25 nm and are composed of SnO2 nanoparticles as confirmed by X-ray diffraction experime...
Article
We report a novel kinetic approach to identify volatile organic compounds (VOCs) and to determine their concentrations with a single SnO2 gas sensor. Traditional array-based electronic noses usually rely on the saturation level of the response between target molecules and sensing materials, and our approach is kinetic based. It is more straightforw...
Article
In this paper, we report a synthetic route for mesoporous metal oxides from inorganic metal sources in aqueous media. This synthesis route offers a versatile, low cost and environmental friendly method to produce mesoporous metal oxides that have very high surface areas. As an example, the synthesis of iron oxide is described in detail. Synthesis c...
