摘　　要：非均相催化臭氧氧化技术是一种高效的水污染控制技术。负载型稀土臭氧氧化催化剂因稀土元素独特的电子构型,展现出优异的催化性能,不仅具有良好的稳定性和较长的使用寿命,还可有效解决催化剂流失及出水金属离子超标问题,被认为是最有前景的非均相臭氧氧化催化剂。本文着重从负载型稀土臭氧氧化催化剂的制备、催化反应机理以及单稀土、稀土-过渡金属、双稀土-过渡金属氧化物负载型臭氧氧化催化剂在近几年的污水处理领域中的应用进展进行概述与总结。多稀土复合型非均相臭氧氧化催化剂的开发,以及对催化氧化过程的作用机理的深入研究,是未来非均相催化臭氧氧化技术在水处理中的重点研究方向。Heterogeneous catalytic ozonation technology is an efficient water pollution control technology.Due to the unique electronic structure of rare earth elements,the supported rare-earth ozone oxidation catalysts exhibit good catalytic performance,excellent stability and long service life,but can effectively solve the problem of catalyst loss and exceeding the standard of metal ions,which have been regarded as the most promising heterogeneous ozone oxidation catalysts.This review summarizes the preparation technology of supported rare-earth ozone oxidation catalysts,catalytic ozonation reaction mechanism and the application progress in the field of wastewater treatment in recent years for the supported single rare-earth oxide,rare earth-transition metal oxide and binary rare-earth oxide ozone oxidation catalysts.The development of multi-rare earth composite heterogeneous ozone oxidation catalysts and the in-depth study of catalytic reaction mechanism are the key research direction in the future.
