摘　　要：微波作为一种新型高效的加热制备技术,在材料化学领域中表现出清洁、高效、耗能少、收率高以及选择性好等优点,使其在材料制备等领域得到了广泛的应用。TiO_(2)由于具有高催化活性、无毒、化学物理性质稳定等优点,在降解环境中的污染物方面受到了极大的关注。将微波加热技术应用在制备TiO_(2)光催化剂中,可减少热处理时间,降低成本,并有效减少TiO_(2)材料的团聚现象,得到了更加均一的产品。综述了近几年来微波辅助制备TiO_(2)光催化剂的5种制备方法:微波水热法、微波溶胶-凝胶法、微波液相沉积法、微波干燥法、微波微乳液法,及其光降解有机污染物中的应用,旨在为促进微波加热技术在TiO_(2)光催化剂领域中的应用发展提供参考。As a new and efficient heating preparation technology,microwave has been widely used in the field of material preparation due to its advantages of cleanness,high efficiency,low energy consumption,high yield and good selectivity.TiO_(2) has attracted great attention in the degradation of pollutants in the environment due to its high catalytic activity,non-toxicity and stable chemical and physical properties.The application of microwave heating technology in the preparation of TiO_(2) photocatalyst can reduce the heat treatment time,the cost,and effectively the agglomeration of TiO_(2) materials,resulting in more uniform products.In this paper,five preparation methods of TiO_(2) photocatalyst assisted by microwave in recent years,microwave hydrothermal method,microwave sol-gel method,microwave liquid phase deposition method,microwave drying method,and microwave microemulsion method were reviewed,and as well as its application in photocatalytic degradation of organic pollutants.The purpose is to provide reference for promoting the application and development of microwave heating technology in the field of TiO_(2) photocatalyst.
