| titleOfInvention | A kind of preparation method of carbon-coated precious metal ultrafine nanoparticles and product thereof |
| abstract | The invention relates to a preparation method of carbon-coated precious metal ultrafine nanoparticles and a product thereof, which belong to the technical field of nanomaterial preparation. The DC arc discharge device is used to complete the process in two steps. The first step is to prepare the precious metal nanoparticle precursor; the second step is to prepare the carbon-coated precious metal ultrafine nanoparticles. The carbon-coated precious metal ultra-fine nanoparticles are nanoparticles with smooth surface, spherical shape and core-shell structure, the particle size is 5-8 nm, and the shell is carbon; the inner core is precious metal ultra-fine single-crystal nanoparticles, the particle size is 2 to 5 nm. The preparation method of the invention has the advantages of convenience, quickness, simple process, large output and low cost, and the prepared product carbon-coated precious metal ultrafine nanoparticles has smooth surface and uniform size, and has wide potential in the fields of chemical catalysis, biomedicine and the like.
