Abstract: Preparation method of a lanthanum ferrite/silver/zinc indium sulfide composite photocatalyst. Includes following steps: dissolving citric acid, an iron-containing compound, and a lanthanum-containing compound in a first dispersant to obtain a first solution; carrying out a hydrothermal reaction on the first solution, prior to washing and drying sequentially, to obtain a first dried sample; calcining the first dried sample to obtain a lanthanum ferrite sample; adding deionized water and a silver nitrate solution in the lanthanum ferrite sample, prior to irradiation under a xenon lamp, and then washing and drying, to obtain a second dried sample; dissolving the second dried sample, zinc chloride, thioacetamide, and indium chloride in a second dispersant to obtain a second solution; and carrying out a hydrothermal reaction on the second solution, prior to washing and drying sequentially to obtain a lanthanum ferrite/silver/zinc indium sulfide composite photocatalyst, which can increase an absorption rate of visible light.
