摘　　要：随着现代科技和工业的快速发展,水资源受到前所未有的污染威胁。光催化降解由于其有效性和多功能性在目前已经成为了解决水污染问题的主流方案之一,并显示出强大的发展潜力。二氧化钛纳米管及其改性材料被广泛用于光催化降解各种污染物,诸如掺杂和复合材料形式的改性手段已被用于增强其光催化剂的性能。本文综述了最近几年掺杂改性二氧化钛纳米管光催化降解污水的研究进展,介绍了目前常用的掺杂改性方法及其优缺点,从金属和非金属两个类别介绍了常用的掺杂元素,最后通过比较掺杂改性后的降解效果对二氧化钛基纳米管材料降解污水进行了总结和展望。With the rapid development of modern technology and industry, water resources are threatened by unprecedented pollution. Photocatalytic degradation has become one of the mainstream solutions to water pollution problems due to its effectiveness and versatility, and has shown strong potential for development. Titanium dioxide nanotubes and their modified materials are widely used for photocatalytic degradation of various pollutants, and modification methods such as doping and composite materials have been used to enhance their photocatalytic performance. In this paper, the research progress of photocatalytic degradation of wastewater by dopant modified titanium dioxide nanotube in recent years is reviewed, the commonly used doping modification methods and their advantages and disadvantages are introduced, and the commonly used doping elements are introduced from the two categories of metal and non-metal. Finally, the summary and prospective outlook were reached by comparing the wastewater degradation effect of doping modified titanium dioxide nanotube materials.
