- •
The CO2 hydrogenation over Cu·ZnO supported on Al2O3 and Nb2O5 was studied.
- •
Catalysts were prepared by precipitation or impregnation of the metals over the supports.
- •
Catalysts were characterized by XRF, XRD, TPR, BET area, TPD of n-butylamine.
- •
The catalyst prepared by impregnation of the metals on Al2O3 was the most active and selective to DME.
- •
Results may be explained in terms of the reducibility of the Cu species.
