“…Highly active methanol synthesis catalysts must possess a few characteristics such as a high surface area of the metal function, defect formation in copper nanoparticles, and, lastly, strong metal-support interaction (SMSI). 28,29 Several bimetallic compounds supported on metal oxides are employed in the CO 2 hydrogenation reaction for methanol synthesis, such as Cu-Zn, Pd-Ga, Cu-Ce, Cu-Fe, Ni-Ga, etc. 20,[29][30][31][32][33][34][35] Among them, Cu-ZnO based catalysts have shown the highest efficiency in terms of yield and cost.…”
