Abstract:
Nitrogen-doped graphene nanosheets (N-GNSs) displayed a discharge capacity two times greater than their pristine counterpart, as well as superior electrocatalytic activity as a cathode material for sodium-air batteries. The enhanced performance of N-GNSs is attributed to the active sites introduced by nitrogen doping.
