Description

technical field The invention relates to a preparation method of a carbon-coated copper micro-nano particle composite material, which belongs to the technical field of carbon material synthesis. Background technique The core / shell nanostructure with inorganic or organic matter as the shell has excellent physical and chemical properties, which has aroused great interest of researchers. Among them, the carbon-coated metal (M / C) structure, especially Cu / C For example, due to their inexpensive and unique properties, they have been intensively studied for their wide applications in biosensors, supercapacitors, fuel cells, and catalysts, etc. After carbon coating, it not only retains the unique electromagnetic and optical properties of this Cu particle, but also endows it with better chemical stability, acid and alkali resistance, biocompatibility and surface functionalization. Microparticles can be modified to expand their wider applications. So far, many methods have been deve...
