| Abstract: | Cu/ZnO/Al2O3 catalysts were prepared by mechanical milling and combustion at different calcination temperatures and were tested for the synthesis of methanol from CO hydrogenation.Calcination of catalyst precursors was monitored with thermogravimetry differential scanning calorimeter(TG-DSC).These catalysts were characterized by X-ray diffraction(XRD),scanning electronic microscope(SEM),N2 adsorption,temperature-programmed reduction with H2(TPR) and N2O oxidation followed by H2 titration.The results showed that the physicochemical properties of the prepared catalysts depended strongly on calcination temperature,and BET surface area and dispersion of copper species decreased with increasing calcination temperature.The catalyst calcined at 350℃ exhibited the highest activity and stable catalytic performance.The method could be a promising alternative for the preparation of highly efficient Cu/ZnO/Al2O3 catalysts. |
