Metal Oxide/TiO₂ Hybrid Nanotubes Fabricated through the Organogel Route.

ABSTRACT: Titanium dioxide (TiO₂) nanotube and its hybrid nanotubes (with various metal oxides such as Ta₂O₅, Nb₂O₅, ZrO_2, and SiO₂) were fabricated by the sol-gel polymerization in the ethanol gels formed by simple l-lysine-based organogelator. The self-assembled nanofibers (gel fibers) formed by the gelator functioned as a template. The different calcination temperatures gave TiO₂ nanotubes with various crystalline structures; e.g., anatase TiO₂ nanotube was obtained by calcination at 600 °C, and rutile TiO₂ nanotube was fabricated at a calcination temperature of 750 °C. In the metal oxide/TiO₂ hybrid nanotubes, the metal oxide species were uniformly dispersed in the TiO₂ nanotube, and the percent content of metal oxide species was found to correspond closely to the feed ratio of the ra
