Influence of modifier (Mn, La, Ce, Zr and Y) on the performance of Cu/Zn/Al catalysts via hydrotalcite-like precursors for CO2 hydrogenation to methanol

A series of promoted Cu/Zn/Al catalysts derived from hydrotalcite-like precursors were synthesized by co-precipitation method and tested for the CO2 hydrogenation to methanol. The influence of modifier (Mn, La, Ce, Zr and Y) on the physicochemical properties of Cu/Zn/Al catalysts was studied in detail. The results show that the BET specific surface area, Cu surface area and Cu dispersion increase in the order of Cu/Zn/Al < Cu/Zn/Al/Mn <...
