Mesoporous hybrid material composed of Mn_3O_4 nanoparticles on nitrogen-doped graphene for highly efficient oxygen reduction reaction

摘要

The hybrid material composed of Mn_3O_4 nanoparticles on nitrogen-doped graphene was prepared via a sorvothermal process and investigated for the first time as a catalyst for oxygen reduction reaction (ORR). Its high ORR activity, excellent durability and tolerance to metnanol make this hybrid material a promising candidate for highly efficient ORR in fuel cells and metal-air batteries.
