Description
Summary:TiO2 is one of the most studied compounds in materials science. Owing to some outstanding properties it is used for instance in photocatalysis, dye‐sensitized solar cells, and biomedical devices. In 1999, first reports showed the feasibility to grow highly ordered arrays of TiO2 nanotubes by a simple but optimized electrochemical anodization of a titanium metal sheet. This finding stimulated intense research activities that focused on growth, modification, properties, and applications of these one‐dimensional nanostructures. This review attempts to cover all these aspects, including underlying principles and key functional features of TiO2, in a comprehensive way and also indicates potential future directions of the field. A new escapade for titania: Titanium dioxide is one of the most studied materials and has many applications, for example in photocatalysis, dye‐sensitized solar cells, and biomedical devices. TiO2 nanotubes, which have outstanding properties and have resulted in much research interest, play a particularly important part.
