▎ 摘　　要

NOVELTY - Preparing graphene-type embedded metal nano-particle comprises placing small organic molecules as carbon source in a quartz boat, and directly depositing on a metal substrate by using atmospheric physical meteorological transmission process to obtain final product. USE - The metal nanoparticle is useful as electro-catalyst in electrolytic water oxygen evolution reaction (claimed). ADVANTAGE - The method: utilizes solid phase migration method to synthesize embedded graphene nano-sheet catalyst in interconnected metal nano particles, which has porous and large surface area, excellent conductivity and mechanical stability to the active site, and can provides more active sites; is suitable industrial production; and produces product as electro-catalyst, which is low cost, safe and environment-friendly. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for graphene-type embedded metal nano-particle prepared by above method.
