Preparation method of molybdic sulfide nanosheet/sliver nanoparticle composite material

The invention belongs to the technical field of semiconductor material preparation processes and relates to a molybdic sulfide nanosheet/sliver nanoparticle composite material prepared by a simple liquid-phase stripping and wet chemical method. The preparation method is characterized in that the molybdic sulfide nanosheet/sliver nanoparticle composite material is prepared by the simple liquid-phase stripping and wet chemical method. The process is simple, convenient and easy to implement and low in equipment requirement, the composite material prepared by the method is small in impurity content, and silver nanoparticles generated on the surface layer of a molybdic sulfide nanosheet are small in grain size, random in distribution and high in bonding strength with the molybdic sulfide nanosheet. The sliver nanoparticles are closely adsorbed on the molybdic sulfide nanosheet, and the composite material has high surface enhanced Raman scattering effect, so that application range of the composite material in the field of bioprobes is widened.
