Nonprecious metal (NPM) catalysts are considered as the most promising candidate to replace Pt‐based electrocatalysts for oxygen reduction reaction (ORR). However, in comparison with the commercial Pt catalyst, the development of high efficiency and low cost NPM catalysts for ORR still remains a big challenge. Here, a simple but efficient way to fabricate porous N‐doped graphene immobilized molybdenum nitride (MoN) nanoparticles is reported, and simultaneously, the introduction of H 2 O 2 plays a key role in modulating the particle size of MoN and the microstructure of the composite to achieve different configuration. As results, it is shown that the as‐prepared material owns outstanding ORR activity and excellent stability in an alkaline medium. To the best knowledge, this catalyst possesses the best performance among the same class catalysts as reported. It is believed that the H 2 O 2 ‐assisted strategy can provide new insights in synthesis of high efficient metal nitride/carbon hybrid materials toward advanced energy conversion and storage.
