In the hydrogenation of CO₂ to methanol over mixed oxide catalysts, strong adsorption of CO₂ and formate is a barrier to H₂ dissociation. In this study, we synthesized a Co-In doped ZrO₂ catalyst (Co-In-ZrO₂) containing atomically dispersed Co and In to suppress the poisoning effect. In this catalyst, the Co site was responsible for the adsorption of CO₂ and formate, while the adjacent In atom promoted the hydrogenation of the adsorbed intermediate to methanol by dissociating H₂.
