摘      要：Energy crisis and environmental problems urgently drive the proposal of new strategies to improve human wellbeing and assist sustainable *** this end,scientists have explored many metal oxides-based photocatalysts with high stability,low cost,earth abundance,and potentially high catalytic activity relevant for key applications such as H2O splitting,CO2 reduction,N2 fixation,and advanced oxidation of *** these metal oxides,oxygen vacancies(OVs)are ubiquitous and intrinsic defects with pronounced impacts on the physicochemical properties of the catalysts,which may open new opportunities for obtaining efficient metal *** thorough understanding of the structural and electronic nature of OVs is necessary to determine how they serve as catalytically active *** this review,we summarize the origin of OVs,the strategies to introduce OVs,as well as the fundamental structure-activity relationships to relate these crystal defects to catalyst properties including light absorption,charge separation,*** emphasize the mechanism of OVs formation and their effects on the intrinsic catalytic characteristics of the metal *** also present some multicomponent catalytic platforms where OVs contribute to catalysis via ***,opportunities and challenges on engineering defects in photocatalysts are summarized to highlight the future directions of this research field.
