The invention belongs to the technical field of new materials, and relates to a bismuth/bismuth oxychloride microsphere photocatalyst as well as a preparation method and application thereof. The preparation method comprises the following steps: uniformly mixing a bismuth source, a chlorine source and an organic solvent, and then carrying out solvothermal reaction on the mixed materials, thereby obtaining the bismuth-chlorine-doped bismuth oxide, wherein the organic solvent is N, N-dimethyl formamide. According to the invention, the problem of two-dimensional structure aggregation of the BiOCl nanosheet is solved, the in-situ growth enables the interface coupling between Bi and BiOCl to be tight, the problem of charge separation resistance is solved, and the properties of a sample in optics and electrics can be adjusted. Meanwhile, oxidative degradation of pollutants can be carried out under visible light. 本发明属于新材料技术领域，涉及一种铋/氯氧化铋微球光催化剂及其制备方法与应用。其制备方法为：将铋源、氯源与有机溶剂混合均匀，然后将混合后的物料进行溶剂热反应，反应后即得；其中，所述有机溶剂为N,N-二甲基甲酰胺
