Template synthesis and characterization of WO3/TiO2composite nanotubes

Abstract
Highly ordered WO3/TiO2 composite nanotubes have been successfully prepared by the combination of the sol-gel chemical method and the anodic aluminium oxide (AAO) templating method. The diameter of the WO3/TiO2 composite nanotubes is about 100 nm, which is in good agreement with the pore diameter of the AAO template. The composite nanotubes are composed of mixed oxides of W 6+ and Ti 4+ .
