Effect of secondary heteroatom (S, P) in N-doped reduced graphene oxide catalysts to oxygen reduction reaction

Heteroatomic dual-doped metal free graphene materials have revealed significant improvement in the electrocatalysis properties for oxygen reduction reaction (ORR) in alkaline anion exchange membrane fuel cells. Here we report a straightforward and cost-effective strategy to fabricate N, S- and N, P-...
