Abstract: The invention provides a titanium carbide nanosheet/layered indium sulfide heterojunction and an application of the same in degrading and removing water pollutants. A simple electrostatic self-assembly method is used to uniformly absorb indium ions on the surfaces of Ti3C2 nanosheets, which effectively inhibits the stacking of the nanosheets and is beneficial to the uniform growth of In2S3 nanosheets on the surfaces of the Ti3C2. The present invent overcomes two disadvantages of too fast photogenerated carrier recombination rate of In2S3 and easy agglomeration of nano-scale In2S3, and effectively improves the separation efficiency and photocatalytic activity of photogenerated electron-hole of In2S3.

Abstract: The invention discloses a phosphorus-doped tubular carbon nitride micro-nano material and application thereof in waste gas treatment. Melamine is partially hydrolyzed into cyanuric acid through a phosphorous acid-assisted hydrothermal method to form a melamine-cyanuric acid super molecular precursor; the center of the precursor starts to be pyrolyzed under heating calcination, and thus phosphorus-doped tubular carbon nitride is obtained; the phosphorus-doped tubular carbon nitride and sodium borohydride are mixed and subjected to low-temperature calcination in an inert gas atmosphere, and defect-modified phosphorus-doped tubular carbon nitride is obtained. The defect-modified phosphorus-doped tubular carbon nitride micro-nano material has a good photocatalytic effect on catalytic degradation of waste gas; besides, the production raw materials are abundant and easy to obtain, and the phosphorus-doped tubular carbon nitride micro-nano material is good in stability and recyclable and has application prospects in waste gas treatment.

Abstract: The present invention disclosed preparation method of a visible-light-driven CC@SnS2/SnO2 composite catalyst, and application thereof, comprising the following steps: preparing CC@SnS2 composite material in a solvent by using SnCl4.5H2O and C2H5NS as raw materials and carbon fiber cloth as a supporting material; calcining said CC@SnS2 composite material to obtain the visible-light-driven CC@SnS2/SnO2 composite catalyst. The present invention overcomes defects of the traditional methods of treating chromium-containing wastewater, including chemical precipitation, adsorption, ion exchange resin and electrolysis, and the photocatalytic technology can make full use of solar light source or artificial light source without adding adsorbent or reducing agent. In this case, the use of semiconductor photocatalyst to convert hexavalent chromium in chromium wastewater into less toxic and easily precipitated trivalent chromium greatly reduces the cost and energy consumption.

Abstract: The present invention provides a method for synthesizing a bifunctional pure organic photocatalytic material with the capabilities of fast adsorption and efficient degradation. By means of reasonably introducing a perylene imide group into an amphiphilic block copolymer, a micelle for treating contaminants in water is formed by self-assembly. The present invention features the advantages in that the micelle formed by self-assembly of the perylene-based amphiphilic block polymer is uniform in size, exhibits ultra-high adsorption capacity on bisphenol A, and can rapidly reach a stable adsorption equilibrium at various concentrations or temperatures. The micelle also demonstrates, in a mixed phenol solution, significant recognition selectivity and good affinity for bisphenol A. In addition, the micelle has rapid degradation efficiency on bisphenol A. The present invention provides a new design concept for the advanced treatment of wastewater by using a metal-free organic material.

Abstract: A method for the low-temperature heat treatment of toluene by using a composite material having a ternary NiO nanosheet @ bimetallic CeCuOx microsheet core-shell structure. The composite material having the ternary NiO nanosheet @ bimetallic CeCuOx microsheet core-shell structure is placed in an environment containing toluene, and is heated at a low temperature to complete the treatment of toluene. The use of precious metal particles loading is avoided for the catalyst, and the costs of materials is thus greatly reduced. Moreover, nickel oxide grows on CeCuOx microsheet nanosheets. The preparation process is relatively simple, and the catalytic performance on toluene is excellent. Therefore, the method has high economical practicability and research value. The 3Ni/CeCuOx catalyst may completely catalyze toluene at 210° C., which has great research significance and certain application prospects for the actual solution of toluene polluted gas in the air environment.
