摘　　要：综述了硅铝复合氧化物的制备方法,主要介绍了溶胶-凝胶法、沉淀法、水热合成法、混合法和浸渍法及其优缺点。溶胶-凝胶法因其可以制得高比表面、大孔径、孔分布集中的硅铝复合氧化物材料被广泛采用。介绍了硅铝复合氧化物材料作为催化剂载体应用于工业生产的现状,及其存在的问题和今后的发展方向。The existing approaches of the synthesis of silica-alumina mixed oxides were reviewed, including sol-gel method, precipitation method, hydrothermal synthesis method, mixing method and impregnation method. Due to the high specific surface area, large pore volume and narrow pore distribution, sol-gel method was widely used. The current situation of the mixed oxides as catalyst support was introduced. Besides, the existing problems and the future directions have also been discussed.
