Review in Water-Assisted Crystallization of TiO2 Nanotubes
TiO2 nanotubes(TNT)have been widely used due to their unique structure and physical prop-erties.Water-assisted crystallization method is both efficient and energy-saving,and can successfully over-come some shortcomings of traditional heat treatment methods.This paper summarizes the latest research progress in TNT water-assisted crystallization,and introduces different synthesis methods.These methods can be used to control the morphology,the size,and the crystal structure of TNT and to explore how amor-phous TNT can transition to crystalline state through water-assisted crystallization as well as the influence of water during the crystallization process.The paper also analyzes the basic properties of TNT prepared by water-assisted crystallization method and their applications in photocatalysis and solar cells.The water-assisted crystallization strategy makes the further research and application of TNT possible.
