Thermocatalytic CO2 hydrogenation with"green"H2 is one of the most promising carbon-negative tech-nologies,wherein oxygen vacancy engineering serves as a novel strategy to boost the catalytic perfor-mance of oxide-containing catalysts.To provide theoretical guidance and promote technical progress in this important field,the status and prospect of oxygen vacancy-boosted thermocatalytic CO2 hydro-genation have been thoroughly reviewed herein.Specifically,fundamentals including origin,construc-tion,characterization,and function of oxygen vacancies will be systematically summarized and oxygen vacancy-boosted hydrogenation reactions including methanation,reverse water-gas shift(RWGS),methanol synthesis,and other hydrogenation processes will be comprehensively introduced.In addition,challenges and opportunities from the perspective of engineering strategies,promoting effects,and medi-ating mechanisms of oxygen vacancies will be succinctly proposed.Overall,this review is expected to gain more insights into the role of oxygen vacancies and shed new light on the design of efficient oxide-containing catalysts.
