▎ 摘　　要

NOVELTY - Nano noble metal composite catalyst comprises three dimensional network structure of graphene. The noble metal nano-particles attached to graphene surface. The graphene surface is coated with polymeric microspheres to obtain polymeric microspheres/graphene nano noble metal particle ternary composite particle. The ternary particles have three-dimensional network structure of graphene. The microspheres have size of 0.5-500 mu m, mass ratio of polymeric microspheres and graphene is 100:0.5-10 and mass ratio of microspheres/graphene composite particle and noble metal nano-particle is 100:2-40. USE - Nano noble metal composite catalyst. ADVANTAGE - The nano noble metal composite catalyst has good permeability, high catalyzing efficiency and high strength.
