“…This is because the methanation of CO 2 is an exothermic reaction, but endothermic for the RWGS reaction, which is favored at high reaction temperatures [21]. Unexpected, higher selectivity of CO was observed at 300 • C compared to that at 400 • C, which was in agreement with the observation on the 10% Co-CeO 2 and Ru/SDC catalyst [9,22], although the underlying reasons were not clear. It was speculated that this might be related to the competitive adsorption activation of CO 2 and H 2 at different temperatures.…”

A Co-based catalyst is a great candidate for the hydrogenation of CO2. Herein, a support-free nanoporous Co catalyst with high surface area and hierarchical pores was prepared by chemical dealloying, which exhibited excellent performance in the reverse water–gas shift (RWGS) reaction. High conversion of 54.2% and RWGS reaction rate of 812 μmolCO2/gcat/s could be obtained at a high weight hourly space velocity.

“…Ru [27], Cu [28][29][30], Fe [31,32], and Ni [33,34] have been utilized. Various supports such as CeO 2 [28,35,36] , SiO 2 [37,38] , Al 2 O 3 [39,40] , ZrO 2 [29] , TiO 2 [25,41] , zeolite [13] have been used. In addition, methanation of CO 2 , also known as Sabatier reaction is a promising strategy for the production of methane.…”

“…Therefore, supported bimetallic catalysts have been extensively used for the RWGSR due to their tuning catalytic activity that may be achieved by two metals working synergistically. The existence of Mo in the structure of the Fe-Mo/Al 2 O 3 catalyst enhances its catalytic performance for the RWGSR due to the electronic effect, which transfers electrons from Fe to Mo and leads to an electron-deficient state of the Fe species, in which it is not helpful for CO adsorption and hence inhibits the continuous hydrogenation of the intermediates (Kharaji et al, 2013;Panaritis et al, 2018). It is reasonable for the Ni species with the electron deficient state to possess high catalytic performance for RWGSR when Ni is added as a second metal component to the Mo/Al 2 O 3 catalyst (Kharaji et al, 2014).…”

The reverse water-gas shift reaction (RWGSR), a crucial stage in the conversion of abundant CO 2 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 the morphologies, compositions, promoting abilities, and presence of strong metal-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.
