中文摘要：
催化臭氧化是降解水中有机污染物的有效途径。为了开发高效稳定的臭氧化催化剂，文章研究了负载稀土的Y型沸石材料。结果表明，负载稀土氧化物的Y沸石具有高的比表面积和表面羟基密度，从而显示了优越的催化臭氧化性能。该辨石材料在5～35℃的室温范围内都体现了较好的催化性能，并且显示了较好的重复使用性能，具有良好的实际应用前景。
英文摘要：
Catalytic ozonation is an effcctive route for degradation of organic pollutants in water. In order to develop efficient and stable ozonation catalyst, Y zeolite loaded with rare earth was studied. The results indicated that the rare earth loaded Y zeolite revealed excellent catalytic properties due to its high surthce area and density of surface hydroxyl groups. The cataltsis of the zeolite was remarkable in the temperature rangc of 5-35 ℃. The stability of the catalyst was proved through reuse experiments. Keywords： loaded; rare earth; Y zeolite; ozone
