▎ 摘　　要

NOVELTY - Preparation of heterogeneous atom doped graphene, involves subjecting hetero atom precursor compound to pyrolysis process at 700-1000 degrees C, under the inert atmosphere, to heterogeneous atom doped graphene. The hetero atom precursor compound is non-metallic atom precursor compound or transition metal atom precursor compound. USE - Preparation of heterogeneous atom doped graphene used as fuel cell cathode oxygen reduction catalyst and metal-air battery cathode bifunctional catalyst (all claimed). ADVANTAGE - The battery is obtained with high charging and discharging capacity and long life time period.
