文摘

Graphene based catalysts design for ORR is demonstrated by combining experiments and modellings. Iron porphyrin like active site is unraveled to be five nitrogen coordinated as FeN5. Cobalt porphyrin like active site is shown to be four nitrogen coordinated as CoN4. Nickel porphyrin like catalyst is potentially used for catalytic synthesis of H2O2.
