description | The invention is suitable for the technical field of photocatalysis, and provides preparation and application of a fibrous CoTiO3 and g-C3N4 composite photocatalyst. The preparation method comprises the following steps: uniformly stirring ethanol, acetic acid, N,N-dimethylformamide, tetrabutyl titanate, cobalt acetate and polyvinylpyrrolidone, adopting an electrostatic spinning technology to obtain a filamentous film, calcining the film in a muffle furnace, and conducting washing and drying to obtain fibrous CoTiO3; and uniformly grinding the CoTiO3 and urea, and calcining the CoTiO3 and the urea to obtain the fibrous CoTiO3 and g-C3N4 composite photocatalyst. The obtained composite photocatalytic material is simple in preparation process, stable in property, good in dispersity and high in adsorption capacity, and can be used for hydrogen production through water photolysis and photocatalytic degradation. After the composite photocatalyst obtained by the method is loaded with 3% of Pt, the hydrogen yield reac |
