摘要
Made to measure: TiO2-Nb2O5 nanotubes are grown on a Ti-Nb alloy (Ti45Nb) by anodization in a fluoride-containing electrolyte (see micrograph), and their lengths and diameters can be controlled by adjusting the potential. The low rate of chemical dissolution of Nb 2O5 in the electrolyte allows the formation of long nanotubes with regular morphology. (Figure Presented). © 2006 Wiley-VCH Verlag GmbH & Co. KGaA.
