UV Photocatalytic Degradation of Toluene and Tetradecane Using Anatase TiO2 Crystals

Saleh Nasser Al-Busafi, Khaled Melghit, and Kawakob N Al-Dughaishi

Crystalline titanium oxide was obtained by simple and low cost method. X-ray diffraction (XRD) measurements confirmed that the prepared TiO2 catalyst has a single anatase structure with no indication of the presence of a secondary phase. Transmission electron microscopy (TEM) micrograph demonstrates that the anatse TiO2 has spherical homogenous crystals with average diameter of 1.10 nm. Toluene and tetradecane adsorbed on the surface of titanium oxide were easily degraded when exposed to UV light. The % removals of toluene and tetradecane at 120 minutes were 84.5 and 98.8 respectively.
