Abstract
The new photocatalysts were prepared from the commercial metatitanic acid (TiO(OH)2) by ethanol treatment. The photocatalytic activity of catalysts thus prepared was studied by degradation of phenol and dyes (Reactive Red (monoazo dye) Direct Green (polyazo dye) in water under artificial solar light irradiation. Introduction of carbon-containing species to the TiO2 was identified from the FTIR/DRS spectra (new bands in the regions 3100-2800 cm-1 and 1750-1400 cm-1). With increasing temperature through ethanol carbonisation, the rate of photodegradation of phenol under artificial solar light irradiation increased and the turbidity of the solution insignificantly decreased. On the UV-Vis/DR spectra of the TiO2/C photocatalysts, the decrease in reflectance in the visible light region was observed. Absorption of visible light by TiO2/C photocatalysts thus prepared can enhance their activity under solar light.
