“…Among Cu-based catalysts,C u/ZnO/Al 2 O 3 and Cu/ ZrO 2 have been shown to be effective in the selective hydrogenation of CO 2 to CH 3 OH. [1,[4][5][6][7][8][9][10][11] ForCu/ZrO 2 ,the selective CO 2 hydrogenation to CH 3 OH is ascribed to Lewis acidic Zr surface sites,l ocated at the periphery of Cu nanoparticles that facilitate the formation of formate and methoxy reaction intermediates. [12,13] Forc omparison, Cu/SiO 2 that does not contain Lewis acidic sites shows significantly lower activity and selectivity favoring CO formation.…”

“…Contributions of the support materials (e.g., alumina) and the implemented synthesis methods (e.g., hydrolysis method) as well as the catalysts' compositions on improving the methanol selectivity and yield can be highlighted for instance by reviewing the reported performances of the non-supported Cu-ZnO catalysts (e.g., item 3) in comparison to the performances of the supported catalysts or the ones synthesized via other methods, while tested under similar operating conditions. Cu/ZnO/Al 2 O 3 , Cu/ZnO/ZrO 2 , Cu/ZrO 2 , Cu/ZnO/Ga 2 O 3 catalysts and other multi-component-oxides supports and promotors have been widely investigated for this application [18,19]. Among them, Al 2 O 3 supported Cu-ZnO catalyst has shown a promising performance in terms of selectivity towards methanol for the practically relevant high range of carbon dioxide conversion so that the methanol yield of more than 20% can be secured [16][17][18].…”

“…Continue following the reported studies listed in Table S1, after reviewing the reported performances of the Cu/ZnO catalysts under low-medium pressure (listed reports in rows10- 19), the performance of the alumina supported catalysts (listed reports in rows show the highest methanol yield as expected to be achieved at the highest operating pressure of 110 bar. Here, the impacts of operating pressure, H 2 /CO 2 ratio, synthesis method as well as the catalyst composition (even some commercial catalysts) can be tracked.…”
