The invention provides a preparation method of a heterojunction photocatalytic composite material. The invention uses ammonium oxalate, oxalic acid, ethylene glycol, ferric chloride, zinc chloride, hydrofluoric acid, tetrabutyl titanate, hexadecyl methyl Ammonium bromide is used as the main raw material, ethylene glycol is used as the reaction solvent, and a photocatalytic material prepared by solvothermal reaction is in-situ composite sheet titanium dioxide on rod-shaped zinc ferrite. The method has the advantages of simple operation, simple equipment, and easy control of the reaction process; the material has relatively strong photocatalytic degradation ability, and has great applications in environmental protection and pollution treatment. Moreover, it also has considerable prospects in photocatalytic water splitting for hydrogen production. |
