▎ 摘　　要

NOVELTY - Manufacturing high performance electrocatalyst involves synthesizing a composite of graphene and multi-walled carbon nanotubes (MWNT) by strong electrostatic interaction between positively surface charged graphene and negatively surface charged MWNT, coating nitrogen containing polymers over hybrid structure to obtain a highly uniform and well controlled coating, heating a pyrolysis chamber in inert gas atmosphere, attaching platinum-3d transition metal alloy nanoparticles on the surface of nitrogen doped hybrid structure by modified polyol reduction technique, where the pyrolysis is carried out at 800° C. USE - The method is useful for manufacturing high performance electrocatalyst for proton exchange membrane fuel cell, which is used in transportation and static power applications and in electrical vehicles. ADVANTAGE - The method provides a high performance electrocatalyst with excellent stability in the lower cost.
