AB  - The rational design of efficient electrocatalysts for oxygen reduction reaction (ORR) is the key to developing fuel cells and metal-air batteries. Carbon-supported iron-based materials, as the most promising electrocatalysts for ORR, have drawn much attention as they are cost-effective and exhibit high activity. In this work, a three-dimensional (3D) Fe3O4-decorated N-doped graphene aerogel (Fe3O4/NGA) catalyst was synthesized following a simple hydrothermal method which was followed by an annealing process. The complex formed between Fe2+ and phenanthroline was first used as the precursor of iron and nitrogen sources to synthesize Fe3O4 nanocrystals. Benefiting from the synergistic effect between the uniformly distributed Fe3O4 nanoparticles and the 3D porous N-doped graphene aerogel, Fe3O4/NGA exhibits good electrocatalytic activity with a half-wave potential of 0.81 V. It also exhibits excellent selectivity with low HO2- yield (
