Reverse water–gas shift (RWGS) reaction is considered as an effective solution for conversion of greenhouse gas the CO2 to CO, but it still suffers from relatively low activity and selectivity at temperatures. Herein, we report catalytic performance mechanism NiInx/SBA-15 with different Ni In (indium) molar ratios RWGS a temperature. The results showed that increment In/Ni ratio in intermetallic alloy compounds (IMCs) inhibits CO* adsorption through "active site isolation" effect, thus improving CO. terms In–Ni IMCs, acts active center isolated by atoms hydrogenation reaction. XRD HRTEM formed IMC were highly dispersed on large surface area SBA-15. It was also demonstrated H2-TPR addition enhanced interaction between support, stability catalyst good anti-sintering. Meanwhile, aggregation charge density obtained additives, verified XPS DFT simulation. After optimizing ratio, NiIn0.5/SBA-15 exhibited 29% 400 °C, 0.1 MPa, 24,000 mL/gcat·h, CO over 99% production rate about 47 mmol/gcat·h, which superior those most reported nickel-based catalysts. At same time, long-time maintained well after 25 h situ DRIFTS reveals change intermediates HCOO* COOH* during activation introduction In, leading rapid desorption avoiding further form CH4, can be CO-TPD. Ni–In IMCs weak capacity are main reason achieving high

Abstract With the continuous increase in CO 2 emissions, primarily from combustion of coal and oil, ecosystem faces a significant threat. Therefore, as an effective method to minimize issue, Reverse Water Gas Shift (RWGS) reaction which converts towards attracts much attention, is environmentally‐friendly mitigate climate change lessen dependence on fossil fuels. Nevertheless, inherent thermodynamic stability kinetic inertness big challenge under mild conditions. In addition, it remains another fundamental RWGS owing selectivity issue caused by further hydrogenation CH 4 . Up till now, series catalysis systems have been developed for reduction produce CO. Herein, research progress well‐performed heterogeneous catalysts were summarized, including catalyst design, catalytic performance mechanism. This review will provide insights into efficient utilization promote development reaction.
