Disposable bamboo chopsticks (DBCs) are difficult to recycle, which inevitably cause secondary pollution. Based on energy and environmental issues, we propose a facile strategy to fabricate floatable photocatalyst (fPC) coated onto DBCs, which can be flexibly used in water purification. The photocatalyst of titania and titanium carbide on bamboo (TiO2/TiC@b) was successfully constructed from TiC-Ti powders and DBCs using a coating technique followed heat treatment in carbon powder, and the fPC exhibited excellent photocatalytic activity under visible light irradation. The analysis results indicate that rutile TiO2 forms on TiC during heat treatment, achieving a low-density material with an average value of approximately 0.5233 g/cm³. The coatings of TiO2/TiC on the bamboo are firm and uniform, with a particle size of about 20–50 nm. XPS results show that a large amount of oxygen vacancies is generated, due to the reaction atmosphere of more carbon and less oxygen, further favoring to narrowing the band gap of TiO2. Furthermore, TiO2 formed on residual TiC would induce the formation of a heterojunction, which effectively inhibits the photogenerated electron–hole recombination via the charge transfer effect. Notably, the degradation of dye Rhodamine B (Rh.B) is 62.4% within 3 h, while a previous adsorption of 36.0% for 1 h. The excellent photocatalytic performance of TiO2/TiC@b can be attributed to the enhanced reaction at the water/air interface due to the reduced light loss in water, improved visible-light response, increased accessible area and charge transfer effect. Our findings show that the proposed strategy achieves a simple, low-cost, and mass-producible method to fabricate fPC onto the used DBCs, which is expected to applied in multiple fields, especially in waste recycling and water treatment.

Here, we propose a two-step pervaporation system with a high-silica CHA (chabazite) membrane, which has sufficient resistance to water and acid, to demonstrate the extraction and condensation of the formic acid formed by electroreduction of CO2. The kinetic diameters of water and formic acid are similar and smaller than the pore size of CHA, while the hydrated electrolyte ions (e.g., K⁺ and Cl⁻) are larger than the pore size of CHA. Consequently, the electrolyte ions are separated from the mixture of water and formic acid in the first desalination process, and then water molecules are easily removed from the mixture in the second dehydration process. From 300 ml of an approximately 3 wt% formic acid aqueous solution containing 0.5 M KCl, 10 ml of 18.2 wt% formic acid was obtained.

... Various chemical functionalizations with antibacterial groups or blends with metal nanoparticles (NPs) and metal oxides can demonstrate the antibacterial activity of NC [17,18]. Noble metallic NPs like Au, Ag, Pt, Pd, etc., and non-metallic oxides like ZnO and TiO 2 possess extensive antibacterial and photocatalytic activity [19,20]. In addition, zinc oxide nanoparticles (ZnO NPs) possess strong UV absorption capability, photocatalytic activity and good stability [19][20][21]. ...

... [24,25] Anatase is the most studied crystal form due to the ease of controlling the exposed facet, high activity, and simple construction of heterostructure, oxygen vacancy, and schottky contact. [26][27][28][29] Therefore, it has been extensively studied for photocatalysis and dye-sensitized solar cells, [30,31] and it is also one of the most commonly modified forms. Brookite is a metastable phase of TiO 2 with an orthogonal structure, and has limited content in nature, due to its unstable structure and poor thermal stability, it is less commonly used in photocatalysis. ...

... On the one hand, it was due to the 'Honda-Fujishima effect' of TiO 2 (B) [13]. As shown in Fig. 4i, according to similar mechanisms reported in relevant literature [54][55][56], under UV light irradiation, electrons on the TiO 2 valence band are excited to the conduction band, electrons are negatively charged and holes migrate to the TiO 2 surface. Electron-hole pairs are formed on the surface of TiO 2 , the electrons react with Ti 4+ , and the holes react with surface bridge oxygen ions to form trivalent titanium ions and oxygen vacancies, respectively. ...
