Abstract

We developed a simple method to synthesize TiO₂ nanowire arrays with nearly 100% exposed {001} facets. The coating exhibits good transparency. The thin films of TiO₂ nanowire arrays display a very good photocatalytic degradation of dye molecules and good durability. Based on the above features, the TiO₂ nanowire array coating is advantageous for self-cleaning coating.
