V-modified CuO–ZnO–ZrO2/HZSM-5 catalyst for efficient direct synthesis of DME from CO2 hydrogenation

•A series of V-modified CuO–ZnO–ZrO2/HZSM-5 catalysts were prepared.•V-modified CuO–ZnO–ZrO2/HZSM-5 catalysts show higher catalytic performances.•The catalytic performances are strongly dependent on the content of V added.

A series of V-modified CuO–ZnO–ZrO2/HZSM-5 catalysts for direct synthesis of dimethyl ether (DME) from CO2 hydrogenation were prepared by an oxalate co-precipitation method. The catalysts were also characterized by XRD, BET, H2-TPR, N2O chemisorption, NH3-TPD, and XPS techniques. The results show that the catalytic performances of the catalysts are strongly dependent on the content of V added in the preparation.
