Atomic-scale engineering of indium oxide promotion by palladium for methanol production via CO₂ hydrogenation.

ABSTRACT: Metal promotion is broadly applied to enhance the performance of heterogeneous catalysts to fulfill industrial requirements. Still, generating and quantifying the effect of the promoter speciation that exclusively introduces desired properties and ensures proximity to or accommodation within the active site and durability upon reaction is very challenging. Recently, In₂O₃ was discovered as a highly selective and stable catalyst for green methanol production from CO₂. Activity boosting by promotion with palladium, an efficient H₂-splitter, was partially successful since palladium nanoparticles mediate the parasitic reverse water-gas shift reaction, reducing selectivity, and sinter or alloy with indium, limiting metal utilization and robustness.
