CoMn2O4 nanoparticles anchored on nitrogen-doped graphene nanosheets as bifunctional electrocatalyst for rechargeable zinc–air battery
چکیده انگلیسی


• CoMn2O4/N-rGO for rechargeable zinc–air battery was prepared by hydrothermal method.
• CMO/N-rGO shows improved ORR/OER kinetics in oxygen electrode potential.
• CMO/N-rGO shows overpotential 0.86 for half-cell and 0.7 V for full cell.
• CMO/N-rGO exhibits improved round-trip efficiency with high stability over 100 cycles.

CoMn2O4 nanoparticles supported on N-doped reduced graphene oxide (CoMn2O4/N-rGO), for rechargeable zinc–air battery were prepared by a hydrothermal method. The CoMn2O4 supported on nitrogen-doped graphene oxide showed better oxygen electrode potential compared with CoMn2O4 dispersed on graphene oxide. The zinc–air battery can be reversibly charged/discharged for hundred cycles with a good cycle performance. The improved battery performance of CoMn2O4/N-rGO can be attributed to the synergistic effect of covalently coupling between the nitrogen-doped graphene sheets and spinel cobalt manganese oxide.
