• Visible light activity

New preparation method of rutile phase TiO2 revealing photocatalytic activity under visible light is described. The photocatalysts were prepared using sol-gel synthesis followed by a flash combustion at 850 degrees C. As found, addition of glycerol to the titanium isopropoxide during sol-gel synthesis strongly influences size of TiO2 crystallites. Rutile-type TiO2 obtained showed ability to degrade photocatalytically phenol under visible light. Effectiveness of the mineralisation of phenol was comparable or insignificantly higher than these of commercial TiO2 samples: Evonik P25 and R-001.
