Abstract Photocatalytic CO 2 reduction reaction (CO RR) into high‐value‐added fuels has received significant attention, yet multiple electron and proton processes involved in RR result low selectivity. Herein, a strategy involving oxygen vacancies (Ovs)‐enriched Bi MoO 6 coated on ZIF‐67‐derived Co 3 O 4 to construct well‐defined core‐shell nanocage is developed, which drives effective photoconversion CH with nearly 100% selectivity high apparent quantum efficiency of 2.5% at 420 nm pure water under simulated irradiation. Theoretical calculations experiments exhibit that the potential difference stemming from built‐in electric field provides guarantee for occurring H oxidation set . Numerous exposed Ovs formed Bi─O bond by ethylene glycol mediated approach promotes adsorption charge separation efficiency, can optimize kinetics thermodynamics, facilitating hydrogenation key intermediate *CO generate This work new controlled vacancy generation photocatalysts achieve high‐performance methanation.
