Herein, a series of ternary Ni/In2O3/ZrO2 catalysts is prepared by the two‐step method. In the reaction atmosphere (CO2/H2), In2O3 particles are highly dispersed on the carrier ZrO2, and are partially reduced to form InOx layers. Moreover, In2O3 tends to migrate near Ni species, forming the NiInOx complex structure decorated by InOx layers. It is demonstrated that indium oxide serves as the main active site in the reverse water‐gas conversion reaction, and Ni species function as an auxiliary agent to generate the strong metal‐support interaction effect with indium oxide, facilitate the formation of the key intermediates HCOO* and CO*, and further enhance the CO yield. Ab initio molecular dynamics and density functional theory calculations confirm that the In2O3 clusters have undergone dynamic structural reconstruction on the ZrO2 support driven by temperature, and In2O3 serves as the preferential adsorption site for CO2. 10.1002/cssc.202500664 http://onlinelibrary.wiley.com/termsAndConditions#vor |
