▎ 摘　　要

NOVELTY - Three-dimensional carrier comprises graphene oxide, and functionalized carbon nanotubes. The raw materials of the functionalization carbon nanometre tube comprises a pre-treated carbon nanonetubes and a polydiallyl dimethyl ammonium chloride solution, where the pre-processed carbon nanetubes are prepared by mixing the carbon nano-tube and the acid solution. USE - Three-dimensional carrier for proton exchange membrane fuel cell used in fixed power station and traffic transportation field. ADVANTAGE - The three-dimensional carrier has high catalytic activity, high stability, and strong metal-carrier interaction, and increases the dispersion site of metal particles, and improves the stability of the metal particles. The carbon nano tube effectively avoids the stack between the graphene sheet layer, and synergistically exerts the graphene and carbon nano-tube large specific surface area, and has high stability. The carrier uniformly disperses the supported metal on the surface of the carrier, thus reducing the size of metal particle size, and improving the effective reaction activity area. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: preparing three-dimensional carrier; a catalyst; and preparing the catalyst. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of a method of a three-dimensional carrier. (Drawing includes non-English language text).
