A 3D cobalt-embedded N,P-doped carbon catalyst was synthesized as a low-cost, stable and highly efficient oxygen reduction reaction activity catalyst.
Effective preparation of a high-performance non-precious metal oxygen reduction electrocatalyst (a Co–N complex on 3D N-doped graphene) by a facile method from low-cost raw materials.
The exploration of low-cost and highly efficient non-platinum electrocatalysts for the oxygen reduction reaction (ORR) is vital for renewable systems.
