Titanium dioxide nanotubes have been intensively concerned and studied in recent years due to their special morphology and highly ordered property. This paper reviewed recent advances in titanium dioxide nanotubes. Three kinds of preparation methods were discussed, including template synthesis, electrochemical anodization and hydrothermal synthesis. On this basis, it described the modification methods of titanium dioxide nanotubes in detail, including doping and compositing. The applications of titanium dioxide nanotubes and composites in the field of environment and energy were introduced briefly. Finally, the future studies on the formation mechanism, morphology control and modification of titanium dioxide nanotubes were proposed.
