Strongly coupled NiCo2O4-rGO hybrid nanosheets are syntheiszed through a cost-effective two-step strategy involving a facile polyol process and subsequent thermal annealing treatment in air. The hybrid nanosheets exhibit impressive electrocatalytic performance for the oxygen reduction reaction (ORR) with a current density and onset potentiol comparable to those of commercial Pt/C catalyts, while having perfect tolerance to methanol.
