▎ 摘　　要

NOVELTY - Graphene-loaded platinum-iron-copper ternary alloy catalyst loaded comprises graphene and platinum-eurosilicate-copper (PtFeCo) nano-particles loaded on graphene. USE - Graphene loaded PtFeCo ternary alloy catalyst loaded by graphene for catalytic oxidation of methanol. Uses include but are not limited to direct-methanol fuel cell (DMFC), diesel fuel cell, ethanol fuel cell and biodiesel fuel cell. ADVANTAGE - The catalyst has good stability, strong anti-poisoning ability, and has potential for direct methanol fuel cell. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a preparation method of the catalyst which comprises mixing the graphene oxide with glycol and mixing with the water-soluble platinum source compound, water-soluble trivalent iron source compound and water-soluble cobalt source compound, and heating. Sodium borohydride is added to react, and continuously heated to obtain the catalyst.
