TiO2 nanotubes grown in different organic electrolytes: Two‐size self‐organization, single vs. double‐walled tubes, and giant diameters

Abstract Anodic, self‐organized TiO 2 nanotubes were grown in different organic, fluoride ion containing electrolytes. The present work reports on a number of fundamental differences in tube morphology and composition, if nanotube layers are grown in either ethylene glycol, diethylene glycol, and dimethyl sulfoxide based electrolytes. magnified image (© 2010 WILEY‐VCH Verlag GmbH & Co.
