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.

Published: March 15, 2024

Abstract Artificial photosynthesis for hydrogen peroxide (H 2 O ) presents a sustainable and environmentally friendly approach to generate clean fuel chemicals. However, the catalytic activity is hindered by challenges such as severe charge recombination, insufficient active sites, poor selectivity. Here, robust strategy proposed regulate electronic structure of catalyst collaborative effect defect engineering dopant. The well designed oxygen‐doped CdS nanorods with S 2− defects Cd 2+ 4 d 10 electron configuration (CdS‐O,S v successfully synthesized, sites around or oxygen atoms exhibit rapid separation, suppressed carrier enhanced utilization. Consequently, remarkable H production rate 1.62 mmol g −1 h under air conditions acquired, an apparent quantum yield (AQY) 9.96% at single wavelength 450 nm. This work provides valuable insights into synergistic between doping on activity.
