摘要：

Nitrogen-doped graphene nanosheets (N-doped GNSs) show a high electrocatalytic activity for the air electrode of Li-air fuel cells based on hybrid electrolytes. N-Doped GNSs exhibit high discharge voltage under acidic conditions, which is near to that of commercial 20 wt% Pt/carbon black usually used in H-2-O-2 fuel cells.
