Bismuth-based photocatalytic material as well as preparation method and application thereof

The invention provides a preparation method of a bismuth photocatalytic material, which comprises the following steps: dissolving cuprous salt and bismuth salt in an organic solvent, and uniformly mixing to obtain a solution A; and adding a bromine source into the solution A, reacting for a period of time at high temperature, and freeze-drying to obtain the product. According to the bismuth-based photocatalytic material prepared by the invention, Cu2O is introduced into a BiOBr catalytic material, so that the photocatalytic effect can be greatly improved, the specific surface area of the catalytic material can be increased, and the adsorption performance of the catalytic material can be enhanced. The preparation method is simple and easy to implement, raw materials are easy to obtain, the cost is low, and the practical application possibility is large. The prepared bismuth-based photocatalytic material has a very excellent photocatalytic degradation effect in the presence of hydrogen peroxide. 本发明提供一种铋系光催化材料的
