A series of CuO–ZnO–ZrO2(CZZ) catalysts with different Zn/Zr ratios were successfully prepared by the co-precipitation method and characterized by the techniques of X-ray diffraction (XRD), N2adsorption, reactive N2O adsorption, H2temperature-programmed reduction (H2-TPR). The catalytic activities of the catalysts were tested for methanol synthesis from CO2hydrogenation. It was found that the increasing of the Zn/Zr ratio could lead to the increase of the crystallite size of metallic oxide. When the amount of ZnO ranged from 20% to 80%, the CZZ catalysts exhibited a better activity. It revealed that both Zn and Zr were important parameter for Cu-based catalysts, which were interacted with each other.
