摘要：

A hybrid electrocatalyst CoO/r-NLG with a high density of pyridinic-N-Co bonds was synthesized via pyrolysis treatments of a mixture of cobalt iron precursors and laser-induced mesoporous N-doped graphene, which achieved superb reversible ORR/OER activities, offering a low efficiency loss (E) of 0.635 V in a 1.0 M KOH electrolyte.
