Cu/ZnO/Al2O3 catalysts are widely used in methanol synthesis due to their low cost and high catalytic activity. The structural surface characteristics of Cu crucial the formation active sites for production. In this study, a series methods employed modulate catalyst structure efficiency hydrogenation CO2 methanol. A correlation activity with Cu0 area particle sizes has been established. derived from hydrotalcite-like precursor (CZA-LDH) exhibits maximum specific area, smallest size, dispersion elements, yielding largest production rate, which is comparable commercial catalyst. Stability testing shows that CZA-LDH can retain ∼94% initial situ Fourier transform infrared spectroscopy analysis indicates HCOO*, CH3O* intermediates, product CH3OH generated on surface, reaction follows formate pathway.

Exploiting stable active structures and investigating the intrinsic mechanism are of great importance for heterogeneous catalysis. Especially CO2 hydrogenation to methanol, efficient affordable catalysts desired exert value this reaction in promoting development circular carbon economy. In work, a CoIn3 intermetallic compound (IMC) catalyst with regular arrangement atoms was prepared, which manifests prominent catalytic performance methanol. Systematic atomic-scale investigations reveal critical role unique interatomic interactions ordered atomically aligned IMC catalyst, particularly propelling adsorption conversion reactants while preserving durability. situ measurements density functional theory calculations further demonstrate that path can encounter low activation energy barrier on IMC, thus allowing smooth productive methanol synthesis along HCOO* path. This work provides valuable insights designing inherent hydrogenation.
