Abstract Decorating single atoms of transition metals on MXenes to enhance the electrocatalytic properties resulting composites is a useful strategy for developing efficient electrocatalysts, and mechanisms behind this enhancement are under intense scrutiny. Herein, we anchored Co onto several commonly used MXene substrates (V 2 CT x , Nb Ti 3 C T ) systematically studied behavior oxygen hydrogen evolution reactions (OER HER, respectively) composites. Co@V composite displays an OER overpotential 242 mV HER 35 at 10 mA cm −2 in 1.0 M KOH electrolyte, which much lower than Co@Nb Co@Ti making it comparable commercial noble metal Pt/C RuO /C electrocatalysts. The experimental theoretical results point out that enhanced bifunctional catalytic performance benefits from stronger hybridization between 3d surface terminated O 2p orbitals optimized electronic structure composite. This, turn, lowering energy barriers acceleration kinetics case advantage was further validated by its high overall water splitting (1.60 V deliver ). Our study sheds light origins activity substrates, provides guidelines designing MXene‐based image
