The invention discloses a preparation method and application of a ternary double-quantum-dot synergistic Z electron transfer mechanism composite photocatalytic material, and belongs to the technical field of environmental function new materials and photocatalytic degrading.The preparation method comprises the following steps that bismuth tungstate of a micro-nano structure serves as a subject, two quantum dots are introduced to serve as objects, and the bismuth tungstate of the micro-nano structure serves as the object; the ternary double-quantum-dot synergistic Z electron transfer mechanism composite photocatalytic material is obtained through semiconductor host-guest compounding; the two kinds of quantum dots are carbonized polymer dots and cadmium sulfide quantum dots. The composite photocatalytic material has double quantum efficiency and fluorescence upconversion, is beneficial to electron-hole separation, widens the light absorption range of bismuth tungstate and improves the utilization rate of sunligh
