There has been a considerable interest in one-dimensional nanostructures owing to their remarkable characteristics in particular these electronic properties which have been considered to significantly improve the electron transport time and reduce the recombination rate. The range of research area of one-dimensional nanostructures covers meanwhile a wide range of transition metal oxides. Among them, TiO2 is the most widely studied material because of its promising applications in solar-cells, photoelectrochemical hydrogen production, and CO2 reduction etc.. Because, highly aligned TiO2 nanostructures have been suitable semiconductive properties with ~ 3 eV and optimum band-edges to water, fast electron path way, and chemical stability. In order to form such one-dimensional TiO2 nanostructures, a most straight forward approach is considered to direct electrochemical anodic reactions (named anodization) on Ti metal substrate in a dilute fluoride containing electrolyte. This approach is very simple and easy to control dimensions (diameter and length) and structure. In this presentation, we will show the growing mechanism of anodic TiO2 nanostructures and further modification of the anodic structure for energy application such as solar cells, photocatalytic hydrogen evolution.
