The invention relates to the technical field of inorganic nano antibacterial materials, in particular to a preparation method and application of core-shell type Fe3O4/ZnO coated Cu2S/ZnS coated Ag. According to the preparation method, Fe3O4/ZnO is taken as a core, Ag quantum dots with the particle size of about 1.75 nm are loaded on the surface of a carrier by virtue of the characteristics that ZIF-8 is coordinated and combined with Ag < + > and is reduced into AgO at high temperature, so that the Fe3O4/ZnO (at) Cu2S/ZnS (at) Ag composite material is prepared, the problem of agglomeration of nano Ag with the ultra-small particle size can be solved, the yield of. OH in ROS can be improved by virtue of the composite material Fe3O4/ZnO (at) Cu2S/ZnS (at) Ag and the Ag quantum dots, and the ROS has relatively strong antibacterial activity, and meanwhile, Zn, Fe, Ag and Ag are combined, so that the composite material has relatively good antibacterial activity. Cu and S are doped, so that the material has lower tox
