With the continuous increase in CO2 emissions, primarily from
the combustion of coal and oil, the ecosystem faces a
significant threat. Therefore, as an effective method to minimize
the issue, the Reverse Water Gas Shift (RWGS) reaction which
converts CO2 towards CO attracts much attention, is an environmentally-friendly
method to mitigate climate change and lessen
dependence on fossil fuels. Nevertheless, the inherent thermodynamic
stability and kinetic inertness of CO2 is a big challenge
under mild conditions. In addition, it remains another fundamental
challenge in RWGS reaction owing to CO selectivity
issue caused by CO2 further hydrogenation towards CH4. Up till
now, a series of catalysis systems have been developed for CO2
reduction reaction to produce CO. Herein, the research progress
of the well-performed heterogeneous catalysts for the RWGS
reaction were summarized, including the catalyst design,
catalytic performance and reaction mechanism. This review will
provide insights into efficient utilization of CO2 and promote
the development of RWGS reaction.
