Fig. 5.5 Schematic representation of mechanisms of carbon dioxide hydrogenation to methanol
on (a) Cu–ZnO–ZrO 2 catalyst—ZrO 2 plays the role of the Cu/ZnO active part dispersant, participates in carbon dioxide adsorption and its successive hydrogenation—and (b) Cu–ZnO–Al 2 O 3
catalyst, Al 2 O 3 plays only the role in Cu/ZnO dispersion
