Title
A new method for preparation of rutile phase titania photoactive under visible light
Abstract

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 °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.
