The invention discloses a preparation method of a sulfur doped bismuth powder photocatalytic material. Five bismuth nitrate is placed in a reaction container and added to a solution of nitric acid and stirred to the transparent solution. The hydrochloric acid solution is added to the transparent solution and is stirred after stirring at normal temperature. The solution is rinsed until the solution is neutral and is removed and deposited in a drying box after the solution is neutral. BiOCl was obtained in the drying process, and BiOCl was placed in the reaction container and added to the solution of hydrochloric acid and stirred to BiOCl to completely dissolve, and thioacetamide was added to the above solution to completely dissolve thioacetamide, and the solution was dripped into the anhydrous ethanol, and then the obtained mixed solution was dried to get sulfur doped chloro oxygen in the drying box. Bismuth powder photocatalytic material. The preparation process of the invention is simple and the preparation period is relatively short. The sulfur doped bismuth chloride powder photocatalyst has great utilization rate of light wave in the wavelength range of 350 550nm visible light, and has potential application value in the field of photoelectric materials.
