Abstract

The invention relates to a method for solid-phase preparation of a zinc sulfide-active carbon composite material, belonging to the field of preparation of nano-materials. According to the method, zinc acetate, sodium dodecyl sulfate, thioacetamide and active carbon are successively subjected to mixing, grinding and a reaction under a room temperature condition so as to realize low-heat solid-phase synthesis of the zinc sulfide-active carbon composite material. The low-heat solid-phase chemical method for preparation of the zinc sulfide-active carbon composite material has the characteristics of simple operation, no usage of any solvent, high yield, low cost, simple synthesis process, etc. The zinc sulfide-active carbon composite material prepared in the invention has a large specific surface area and high reaction activity and has latent application prospects in fields like photoelectric device and photocatalysis.

Description

technical field [0001] The invention relates to a method for preparing a zinc sulfide-activated carbon composite material by a solid phase method, and belongs to the field of nanometer material preparation. Background technique [0002] In recent years, nanomaterials have attracted extensive attention of researchers because of their unique physical and chemical properties. As a very important semiconductor nanomaterial, zinc sulfide shows great application prospects in semiconductor light-emitting devices, nonlinear optical materials, photocatalysis and other fields because of its specific optical, electrical, thermal, magnetic and other properties. However, ZnS semiconductor material has a wide band gap and weak absorption of visible light, which is an important factor restricting its practical application. Therefore, the research on the modification of ZnS photocatalyst is a very important research field. Studies have found that activated carbon is favored by researc...
