The preparation method comprises the following steps of: dissolving graphene oxide in water, and ultrasonically treating to obtain graphene oxide dispersing liquid; adding silver acetate into the graphene oxide dispersing liquid, and evenly stirring, to obtain mixed solution; slowly dropping prepared disodium hydrogen phosphate or sodium dihydrogen phosphate solution into the mixed solution of the graphene oxide and the silver acetate to continuously stir for a while; and repeatedly washing products obtained by reaction with deionized water and absolute ethyl alcohol, and carrying out vacuum drying to obtain the graphene oxide / silver phosphate nano-composite visible light catalyst. The invention has the advantages that the invention is wide in raw material source, and simple in preparation process, the obtained composite material is better in structure and feature, and the prepared nano-composite light catalyst is high-efficiency in degradation effect to the organic dyestuff rhodamine B and the methylene blue under the irradiation of visible light due to the structural advantage.
