Enhanced photoelectrochemical activities of a nanocomposite film with a bamboo leaf-like structured TiO(2) layer on TiO(2) nanotube arrays

Abstract

A novel nanocomposite TiO(2) film consisting of a bamboo leaf-like nano TiO(2) layer on a nanotubular TiO(2) arrays surface is synthesized by electrochemical anodization with wet chemical pretreatment; it shows almost three times higher activity as compared to that of nanotubular TiO(2) arrays alone.
