A titanium-modified γ-alumina-supported CuO catalyst has been prepared and used for methanol synthesis from CO2 hydrogenation. XRD and TPR were used to characterize the phase, reduction property and particle size of the reduced catalyst. The addition of Ti to the CuO/γ-Al2O3 catalyst made the copper in the catalyst exist in much smaller crystallites and exhibit an amorphous-like structure. The adding...
HZSM-5 supported copper–molybdenum oxide prepared by an impregnation method has been applied for the first time in the hydrogenation of CO2. The effect of the loading of Mo, the reaction temperature and the stability of hydrogenation of CO2 were investigated. The results indicate that adding a small amount of Mo (Mo/Cu = 1/2 wt) markedly enhances the catalytic activity. The highest DME selectivity...
