The reverse water-gas shift reaction (RWGSR), a crucial stage in the conversion of
abundant CO2 into chemicals or hydrocarbon fuels, has attracted extensive attention
as a renewable system to synthesize fuels by non-traditional routes. There have been
persistent efforts to synthesize catalysts for industrial applications, with attention given
to the catalytic activity, CO selectivity, and thermal stability. In this review, we describe
the thermodynamics, kinetics, and atomic-level mechanisms of the RWGSR in relation
to efficient RWGSR catalysts consisting of supported catalysts and oxide catalysts. In
addition, we rationally classify, summarize, and analyze the effects of physicochemical
properties, such as themorphologies, compositions, promoting abilities, and presence of
strongmetal-support interactions (SMSI), on the catalytic performance and CO selectivity
in the RWGSR over supported catalysts. Regarding oxide catalysts (i.e., pure oxides,
spinel, solid solution, and perovskite-type oxides), we emphasize the relationships
among their surface structure, oxygen storage capacity (OSC), and catalytic performance
in the RWGSR. Furthermore, the abilities of perovskite-type oxides to enhance the
RWGSR with chemical looping cycles (RWGSR-CL) are systematically illustrated. These
systematic introductions shed light on development of catalysts with high performance
in RWGSR.
