In recent years, titanium dioxide (TiO2) nanotubes have attracted much attention within both scientific and industrial domains, primarily owing to their exceptional photocatalytic properties and numerous other attributes. In particular, they are of wide interest including pharmaceuticals, gas detection sensors, renewable energy sources, biomedicine and other branches. However, their application presents certain challenges. Given that their inner cavities are confined to the visible light spectrum, the need for doping with metals arises to expand their physicochemical capabilities. Therefore, achieving precise nanotube synthesis tailored to industrial requirements becomes a paramount consideration. In this study, we introduce the proposed models for the synthesis of TiO2 nanotubes, elucidate the influencing factors, and draw conclusions regarding the synthesis’s impact and the mechanisms underlying TiO2 nanotube formation. However, our primary focus lies on comprehensive analyses and the practical implications of advancing TiO2 technology.
