Review on CO₂ Activation via Catalytic Reverse Water‐Gas Shift Reaction

The reverse water-gas shift (RWGS) reaction offers a promising pathway for CO2 utilization by converting CO2 and H2
into CO and H2O. This review explores the thermodynamic challenges of the RWGS process, emphasizing the need for
high temperatures to suppress side reactions such as methane and coke formation. For catalytic RWGS reaction, reaction
mechanism and catalytic materials are discussed together with kinetic models to provide an insight into RWGS performance
under varying conditions. Catalyst deactivation mechanisms, particularly metal sintering and coke deposition, are
addressed, with strategies for enhancing catalyst longevity throughmaterial optimization. RWGS applications are discussed,
demonstrating the potential for integrating RWGS into industrial settings.
