Abstract

A one pot gel combustion synthetic strategy has been developed for the first time towards the rapid formation of self-doped black anatase TiO2−x (BAT) using titanium butoxide, diethylene glycol (DEG) and water as the only precursors. This swiftly formed nanoplatform was occupied with a high concentration of surface defect sites, especially Ti3+ and oxygen vacancy sites in excess. The in (lattice) and out (surface) defect states were confirmed by Raman, XPS and TEM analysis. These defect-enriched features enabled 33% more photocatalytic activity for BAT than the commercially available photocatalyst Degussa-P25 under solar illumination.
