摘　　要：与传统的-γAl2O3相比,介孔氧化铝分子筛具有较大的比表面积和较窄的孔径分布,作为工业催化剂或催化剂载体,具有更为广阔的应用前景。本文重点介绍了介孔氧化铝分子筛的不同合成方法、结构表征方法和催化性能,分析了模板剂类型、凝胶pH值、洗涤方法、焙烧方式等制备条件对其结构的影响。并对其催化应用进行了评述和展望。Compared with conventional γ-Al2O3, mesoporous alumina molecular sieve has the higher potential in catalysis because of the higher surface areas with a narrow pore size distribution, This review encompasses various synthesis approaches, characterizing methods and catalytic performance of organized mesoporous alumina molecular sieve. The influences of types of templating agents, pH value of the gel, washing treatment and calcined methods on the structure of the mesoporous alumina are also discussed as well. Various characterizations of the mesoporous alumina are introduced in details. Further more, the potential applications in catalysis of organized mesoporous alumina are commented. The research directions of this area in the future are proposed.
