Hydrogenation of carbon dioxide over silver promoted copper/zirconia catalysts

Ni5Ga3 catalysts for CO2 reduction to methanol: Exploring the role of Ga surface oxidation/reduction on catalytic activity

“…For example, due to the issues involving CO2 noted above, copper alone is not an active catalyst for CO2 hydrogenation to methanol, active only for CO hydrogenation; the bimetallic nature of the Cu-Zn sites in the commercial Cu/ZnO/Al2O3 catalyst, however, yields high activities for CO2 hydrogenation to methanol [7,14]. The Cu-Zn system is one of many catalyst systems that leverage bimetallic synergies to achieve improved selectivity in methanol synthesis from CO2; related bimetallics include Pd-Cu [15][16][17][18], Ni-Cu [19][20][21], Ag-Cu [22,23], Pt-Cu [24], Pd-Ga [25][26][27][28], Pd-Zn [18], Pd-In [29][30][31][32], and Rh-W [33].…”

Pd-Decorated CNT-Promoted Pd-Ga2O3 Catalyst for Hydrogenation of CO2 to Methanol

“…A number of Cu-based catalysts, especially CuO-ZnO based catalysts modified with different metals or metal oxides, have been reported for methanol synthesis via CO 2 hydrogenation [1][2][3][4][5][6][7]. Nevertheless, the activity and selectivity of the existing CuO-based catalysts were both relatively low in terms of practicability.…”

Influences of particle size and crystallinity of highly loaded CuO/ZrO2 on CO2 hydrogenation to methanol

“…Catalytic hydrogenation of CO 2 to methanol is an attractive pathway as it is an important feedstock . So far, various catalysts for this reaction, such as Cu/ZrO 2 , Cu‐Ag/ZrO 2 , Cu/ZrO 2 /SiO 2 , Cu/ZnO/ZrO 2 , Cu/CeO 2 /TiO 2 , MnO x /m‐CoO x , InO 2 /ZrO 2 , Cu‐In/SiO 2 , Ni‐Ga/SiO 2 , ZnO/ZrO 2 , Pd/ZnO, Pd‐Cu/SiO 2 , and Cu/ZnO/Al 2 O 3 , have been proposed. Among them, the Cu/ZrO 2 catalyst would be a promising candidate because of its activity and selectivity for CO 2 hydrogenation to methanol (S. Tada et al, unpublished data) …”
