The invention belongs to the technical field of the material chemistry and particularly relates to a preparation method of a nano silver phosphate catalyst driven by visible light. According to the invention, the nano silver phosphate photocatalyst which can stably exist is prepared by a method of irradiating by different light sources and carrying out micro-injection of a reactant; and the problem that a product can be decomposed when the preparation is carried out under the condition of the visible light is avoided. Silver phosphate particles prepared by the method are of a sphere cluster structure, have the monomer diameter of 20 to 60nm and have the integral diameter of 60 to 300nm. The specification of the nano silver phosphate catalyst is far less than that of common micron silver phosphate in the market. Due to the small-size effect and the sphere cluster structure, not only is the catalytic effect of the nano photocatalyst obviously improved than that of a micron catalyst, but also the using amount of the catalyst is greatly reduced and the using cost is effectively reduced. Moreover, by changing the type of a surfactant and the light source of irradiating light in the preparation process, the controllable synthesis is implemented on nano silver phosphate with different morphologies.
