文摘
- •
Co and N co-doped graphene mounted with IrO2 nanoparticles was prepared.
- •
The catalyst showed high capacity and good cycling stability in a Li-O2 battery.
- •
The mounting of IrO2 significantly enhanced the OER performance of doped graphene.
- •
The ORR activity apparently was improved by co-doping graphene with Co and N.
