Abstract:TiO2 is one of the most important inorganic materials for its multiple applications. The controllable synthesis of one-dimensional nanostructured TiO2 (1D-TiO2) is a very complex process due to the various morphologies of the 1D-TiO2, such as 1D-TiO2 nanofiber, nanowire, nanobelt, nanorod, nanoribbon, nanotube. Researchers all around the world have developed a variety of controllable synthesis methods, for instance, electrospinning, hydrothermal treatment, template formation and electrochemical anodization. Recent advances in the controllable synthesis of 1D -TiO2 and their applications are presented in this paper. The influences of the synthesis parameters on the structures and morphologies of the as-prepared nanomaterials are systematically analyzed during the controllable synthesis process. And we also present the future development of the 1D -TiO2, providing a reference for the potential morphologies and applications of the 1D-TiO2 nanomaterials.
Key words: nanostructured TiO2; one-dimensional nanostructure; controllable synthesis; physical chemistry properties
