Abstract:

The Reverse Water-Gas Shift(RWGS) reaction,facilitated by the catalytic reaction between carbon dioxide and hydrogen,has become a crucial step in the production of high-value chemicals and fuels such as methanol,low-carbon olefins,aromatics,and gasoline.This review presents an in-depth analysis of the two primary mechanisms of the RWGS reaction:the redox mechanism and the intermediate mechanism.Additionally,recent advancements in RWGS research were comprehensively reviewed,the catalysts employed in this reaction were systematically categorized,analyzed,and summarized.These catalysts encompassed supported metal catalysts,oxide catalysts(including mixed oxides,spinels,and perovskites),and carbide catalysts.Moreover,the industrial applications of the RWGS reaction was analyzed and its future development was prospected.RWGS reaction could serve as an efficient method for integrating technologies like naphtha dehydroaromatization,ethylbenzene dehydrogenation for styrene production,low-carbon alkane dehydrogenation for olefin production,carbon dioxide capture,and synthetic electronic fuel production to realize efficient utilization of CO2.It not only provided theoretical basis and guidance for developing new RWGS reaction catalysts but also offered feasible ideas and references for the future application scenarios of the RWGS reaction.
