Increasing Solar Absorption for Photocatalysis
· When used as a photocatalyst, titanium dioxide (TiO2) absorbs only ultraviolet light, and several approaches, including the use of dopants such as nitrogen, have been taken to narrow the band gap of TiO2. We demonstrated a conceptually different approach to enhancing solar absorption by introducing disorder in the surface layers of nanophase TiO2 through hydrogenation.

To extract titanium from it''s ore, you need to convert the ore (titanium dioxide) to the tetrachloride (TiCl4). This is done by heating the ore, with a mixture of chlorine gas and carbon to produce a liquid with a melting point of 24C. The titanium tetrachloride is then reacted with either sodium or magnesium metal at red hot temperatures either in a vacuum furnace or an argon atmosphere. The
