摘　　要：以甲醇与乙醇一步反应合成异丁醛反应为基础,研究了不同载体对铜基催化剂反应性能的影响。分别以SiO2S、iO2-ZrO2、SiO2-Al2O3、Al2O3和SiO2-TiO2为载体,采用溶胶-凝胶法和浸渍法制备催化剂。采用TPR、XRD和BET等技术对催化剂进行表征。结果表明,复合氧化物特别是SiO2-ZrO2和SiO2-TiO2作载体能提高催化剂的比表面积,活性组分分散好,催化剂的催化性能较好。Influence of support and preparation condition on catalytic behavior of copper-based catalysts for one-step synthesis of butyraldehyde were studied. Copper-based catalysts with different supports （ SiO2、SiO2-ZrO2、SiO2-Al2O3、Al2O3, SiO2-TiO2） were prepared by sol-gel and impregnation method. The catalyst samples were characterized by TPR, XRD and BET. The results indicated that mixed oxides supports, especially SiO2-ZrO2 and SiO2-TiO2, enhanced surface area, improved dispersion of active component and resulted in good catalytic properties of the catalysts.
