Abstract: 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.
