摘要：

Reverse water gas conversion (RWGS) reaction is a key step in the catalytic hydrogenation of carbon dioxide (CO2) to high value-added chemicals and fuels such as methanol, light olefins, aromatics and gasoline, which is of great significance for the utilization of CO2. This review summarizes the research progress of RWGS reaction in recent years, including thermodynamic analysis of RWGS reaction, catalytic mechanisms, selective catalysts and strategies to improve the performance of catalysts. From the perspective of thermodynamics, RWGS reaction is favorable at high temperature, as methanation reaction emerges at low temperature. The mechanisms of RWGS reaction mainly consist of redox mechanism and association mechanism, and the latter further contains a formate route and/or carboxylate route. Compared with other catalyst system, supported metal catalysts commonly exhibit a superior RWGS reaction performance. In addition, the rational design of RWGS reaction catalysts with high reactivity and durability could be realized by adding alkali metal additives, forming bimetallic alloy as well as modulating the metal-support interaction via selecting a good support or reducing the metal particle size. © 2023 Chemical Industry Press.
