▎ 摘　　要

NOVELTY - Metal compound nano catalyst comprises graphene and intermetallic compound nanoparticles supported on graphene. The intermetallic compound nanoparticles include a redox reaction between a transition metal compound and graphene loaded with simple platinum. The intermetallic compound nanoparticles are formed by annealing treatment. The transition metal compound includes zinc acetylacetonate, iron nitrate nonahydrate, cobalt chloride and/or nickel acetylacetonate and the particle size of the intermetallic compound nanoparticles is 2-20 nm. USE - The nano catalyst is useful in preparing fuel cell (Claimed). ADVANTAGE - The metal compound nano catalyst is capable of reducing the use amount of platinum, reducing the cost of the catalyst, and has high catalytic activity compared with the traditional catalyst. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of metal compound nano catalyst.
