Developing efficient and durable non-precious metal catalysts for oxygen electrocatalysis in fuel cells zinc–air batteries remains an urgent issue to be addressed. Herein, a bimetallic CoCe-NC catalyst is synthesized through pyrolysis of Co/Ce co-doped metal–organic frameworks (MOFs), retaining the inherently high surface area MOFs maximize exposure Co-N Ce-N active sites. The electronic interaction between Co Ce atoms effectively modulates adsorption/desorption behavior oxygen-containing intermediates, thereby enhancing intrinsic catalytic activity. In alkaline media, exhibits E1/2 = 0.854 V electrocatalytic capability comparable commercial Pt/C, along with superior methanol resistance durability. Notably, demonstrates overpotential 84 mV lower than Pt/C at 300 mA cm−2 GDE half-cell. When employed as cathode batteries, it open-circuit voltage 1.47 V, peak power density 202 mW cm−2, exceptional cycling
