▎ 摘　　要

NOVELTY - Palladium-copper alloy/reduced graphene oxide composite has a graded porous structure, and porous palladium-copper alloy nanoparticles which are dispersed and supported on the surface of the reduced graphene oxide. USE - Palladium-copper alloy/reduced graphene oxide composite with high electrocatalytic methanol oxidation activity, for use as anode catalyst for direct methanol fuel cells (claimed). ADVANTAGE - The palladium-bismuth-copper alloy/reduced graphene oxide composite has high dispersibility, large specific surface area, high catalytic activity, and improved synergistic effect on electro-catalytic oxidation activity and stability of methanol. The preparation method is simple and easy to operate, reduces raw material cost, avoids high temperature and high pressure, and avoids the need of using stabilizer and organic solvent. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method for preparing palladium-copper alloy/reduced graphene oxide composite with high electrocatalytic methanol oxidation activity.
