Abstract
Self-organized oxide nanostructures grown by controlled anodic oxidation of a metal substrate attracted wide scientific interest due to a broad number of potential applications. The present work gives an overview on growth principles and mechanistic aspects of self-organized TiO2 nanotubular layers and related transition metal oxide nanostructures. In particular, key electrochemical factors that control tube geometry and routes to fabricate advanced TiO2 nanotube geometries and morphologies are discussed. (C) 2010 WILEY-VCH Verlag GmbH & Co.
