比较了浸渍法、草酸盐凝胶共沉淀法和传统水溶液共沉淀法制备Cu/ZrO_2催化剂的优缺点。采用N2吸附、XRD、N2 O化学吸附、XRD、H2-TPR和XPS等技术对催化剂的物理和化学性质进行了表征。结果表明，制备方法对催化剂的组分分散性、微观结构以及甲醇转化率、H2生成量和CO浓度的催化性能有显著影响。具有较高铜比表面积和组分分散度的催化剂在较低温度下具有较高的甲醇转化活性。草酸盐凝胶共沉淀法制备的Cu/ZrO 2催化剂在SRM反应中表现出比传统水溶液共沉淀法和浸渍法制备的催化剂更高的催化活性和更好的长期稳定性。
Several methods (impregnation, oxalate gel–coprecipitation and conventional aqueous coprecipitation) have been comparatively examined for the preparation of binary Cu/ZrO2catalysts for the catalytic production of hydrogen by steam reforming of methanol (SRM). A variety of techniques including N2adsorption, XRD, N2O chemisorption, XRD, H2-TPR, and XPS were used to characterize the physical and chemical properties of the as-obtained catalysts. The results show that the preparation method significantly affects the component dispersion, microstructural properties and the resulting catalytic performance with respect to methanol conversion, H2production and CO concentration. The catalyst with higher specific copper surface area and component dispersion shows higher activity for methanol conversion at lower temperature. The best Cu/ZrO2catalyst has been prepared by an oxalate gel–coprecipitation method, which shows much higher catalytic activity and enhanced long-term stability in the SRM reaction as compared to the catalysts prepared by conventional aqueous–coprecipitation and impregnation methods.
