CO2 Conversion via Low-Temperature RWGS Enabled by Multicomponent Catalysts: Could Transition Metals Outperform Pt?

In the context of CO2 valorisation, the reverse water–gas shift reaction (RWGS) is gathering momentum since it represents a direct route for CO2 reduction to CO. The endothermic nature of the reaction posses a challenge when it comes to process energy demand making necessary the design of effective...
