| titleOfInvention | Preparation method of two-dimensional S-shaped heterojunction composite photocatalyst sulfur-doped porous carbon nitride/defective tungsten oxide |
| abstract | The invention discloses a preparation method of a two-dimensional S-shaped heterojunction composite photocatalyst sulfur-doped porous carbon nitride/defective tungsten oxide. Sulfur-doped porous carbon nitride/defective tungsten oxide (S-pCN/WO) 2.72 ) Is sulfur-doped porous carbon nitride (S-pCN) and defective tungsten oxide (WO) 2.72 ) The preparation method of the two-dimensional S-shaped heterojunction composite photocatalyst which is compositely constructed comprises the following steps: urea and thioacetamide are used as raw materials, and S-pCN is prepared by a simple calcination method; preparing WO by taking tungsten chloride as a raw material and ethanol as a solvent by adopting a solvothermal method 2.72 (ii) a Mixing S-pCN and WO 2.72 Preparation of S-pCN/WO by solvent evaporation induced self-assembly method in ethanol solvent 2.72 . The invention has the advantages that: the method has the advantages of simple process, low cost and wider sunlight utilization range, introduces surface oxygen vacancies to improve the separation capability of electron hole pairs, constructs a built-in electric field on a heterojunction interface to promote the separation of photo-generated charges and improve the redox capability of the composite catalyst, and is expected to realize the capability of degrading sewage and wastewater by high-efficiency photocatalysis. |
