Facile synthesis of an iron doped rutile TiO2 photocatalyst for enhanced visible-light-driven water oxidation

A facile fast hydrolysis route to a three-dimensional flow-like iron doped rutile TiO2 nanostructure is developed. With iron species doping into both the bulk phase and the surface, the bandgap narrowing of rutile TiO2 is realized and the dissociative adsorption of water on the surface is promoted, which accordingly lead to greatly enhanced activity in visible-light-driven water oxidation.
