摘 要：Developing bifunctional electrocatalysts with high activities and long durability for oxygen reduction reaction（ORR） and oxygen evolution reactions（OER） is crucial towards the practical implementations of rechargeable metal-air batteries. Here we report a three-dimensional nanoporous graphene（np-graphene） doped with both N and Ni single atoms/clusters. The pre-doping of N by CVD dramatically increases the Ni doping amount and stability.
