MFCO spinel anchored on N-rGO is synthesized by a two-step hydrothermal method as a bifunctional electrocatalyst. Its physicochemical properties have been characterized and tested, and it is applied to zinc-air batteries. The experimental and theoretical calculations show that the MFCO is uniformly distributed on the surface of N-rGO. When MFCO is anchored on the conducting N-rGO, a synergistic effect occurs between the Co-N bonds, which changes the arrangement of the C-N bonds from the sp
