Abstract
A fuel cell catalyst for oxygen reduction reactions including Pt—Ni—Cu nanoparticles supported on nitrogen-doped mesoporous carbon (MPC) having enhanced activity and durability, and method of making said catalyst. The catalyst is synthesized by employing a solid state chemistry method, which involves thermally pretreating a N-doped MPC to remove moisture from the surface; impregnation of metal precursors on the N-doped MPC under vacuum condition; and reducing the metal precurors in a stream of CO and Hgas mixture.
