Catalytic performance and hydrogen spillover in Cu/ZnO/Al2O3: Insights from DFT calculations on alkali and alkaline earth oxides promoters for CO2 hydrogenation

Catalytic performance and hydrogen spillover in Cu/ZnO/Al2O3: Insights from DFT calculations on alkali and alkaline earth oxides promoters for CO2 hydrogenation

This study evaluates Cu/ZnO/Al2O3 catalysts promoted with K2O, BaO, Cs2O, and SrO for CO2 hydrogenation to methanol, focusing on the effect of synthesis methods. Catalysts prepared via co-precipitation and impregnation were evaluated for activity, selectivity, and stability under industrial conditio...
