摘　　要：TiO_(2)_(2)光催化剂因具有无毒无害、活性高、热稳定性好、持续性长、廉价等特点,在降解有机污染物方面得到广泛应用。TiO_(2)光催化剂的改性和负载技术提高了光催化反应效果,解决了催化剂分离回收的问题。本文综述了离子掺杂改性和负载技术在制备新型二氧化钛光催化剂中的应用,以及对光催化降解甲基橙废水的效果的研究,为研制新型高效二氧化钛光催化剂提供新的思路和理论依据。TiO_(2)photocatalyst has been widely used in the degradation of organic pollutants due to its non-toxic, high activity, good thermal stability, long duration and low cost. The modification and supporting technology of TiO_(2)photocatalyst improved the photocatalytic reaction effect and solved the problem of catalyst separation and recovery. In this paper, the application of ion doping modification and supporting technology in the preparation of novel titanium dioxide photocatalyst and the study of photocatalytic degradation effect of methyl orange wastewater are reviewed, which provides a new idea and theoretical basis for the development of novel high-efficiency titanium dioxide photocatalyst.
