▎ 摘　　要

NOVELTY - Preparing few-layer graphitized carbon-coated cobalt-platinum nanoparticles electrocatalyst, comprises e.g. (i) adding certain amount of carbon carrier and organic solvent into the three-necked flask, where organic solvent is oleylamine and octadecene, dispersing carbon carrier, (ii) taking cobalt acetylacetonate and platinum acetylacetonate as metal precursor, and borane-t-butylamine as reducing agent, (iii) adding product of step (ii) at room temperature, adding n-hexane, ethanol and isopropanol into reaction product, centrifuging and washing many times to obtain cobalt-platinum nanoparticle precursor loaded wrinkled porous graphene, modifying surface with certain density of organic molecular ligands, and placing in an oven to dry, and (iv) subjecting organic molecular ligand-modified cobalt-platinum nanoparticles to suitable high-temperature calcination treatment, converting organic molecular ligands on the surface of the particles into uniform few-layer graphitized carbon. USE - The electrocatalyst is useful in electrocatalysis, proton exchange membrane fuel cells and many other aspects. ADVANTAGE - The method is simple and can be prepared on a large scale; utilizes easy to obtain raw materials; and has low production cost.
