Abstract: The research progress of Al2O3 in heterogeneous catalytic ozonation is reviewed. The degradation of organic compounds by catalytic ozonation and ozone alone is compared，and the important factors of successful catalytic ozonation，in terms of four key aspects，organic compounds adsorption on catalysts，pH value in liquid phase，inorganic ions and ozone decomposition are discussed. Furthermore，the existing problems in the present research are also put forward and the prospects of Al2O3 in water treatment are presented.

摘要： 综述了Al2O3应用于非均相催化臭氧化体系的研究进展，对比了催化体系和单独臭氧体系对水中有机物的去除效果，从催化剂对有机物的吸附、溶液的pH值影响、溶液中存在的无机离子和臭氧的分解机理方面，探讨了影响Al2O3催化臭氧化体系催化效果的主要因素，分析了目前研究中存在的问题，展望了Al2O3催化剂在水处理方面的应用前景。
