Abstract

Not always black and white: Gray TiO2 nanowires with high photocatalytic activity have been successfully synthesized by aluminum-mediated reduction in a two-zone furnace. These wires, which possess a core (TiO(2-x))/shell (TiO2 ) structure, exhibit visible-light and even IR absorption with high photocatalytic activity, far exceeding that of commercial Degussa P25. They show high stability in air and water under solar-light irradiation.
