▎ 摘　　要

NOVELTY - The catalyst has a quasi-one-dimensional carbon nano-coil partially chemically stripped and reduced to form the quasi-two-dimensional graphene. The quasi-two-dimensional graphene and the remaining quasi-one-dimensional carbon nano-coil part connected with the quasi-two-dimensional graphene is taken as a structure basic unit. A nano-porous structure is formed by combining van der Waals force in a three-dimensional space. The surface of the nano-porous structure is loaded with a platinum. USE - Quasi-one/two-dimensional low platinum load catalyst in novel energy filed and for proton exchange membrane fuel cell (PEMFC). ADVANTAGE - The catalyst provides fast electron transport and oxygen molecular diffusion channels for hydrogen fuel cell cathode oxygen reduction reaction, can support small-sized platinum atoms and nanoparticles with high stability and high density by the network structure, provides highly stable and high-density reaction sites for catalytic reactions, and realizes the stable output of large currents of catalyst cathode membranes. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: a method for preparing quasi-one/two-dimensional low platinum load catalyst; and a catalyst material for hydrogen fuel cell cathode. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart view of the quasi-one/two-dimensional low platinum load catalyst (Drawing includes non-English language text).
