PREPARATION AND CHARACTERIZATION OF TITANIUM(IV) OXIDE PHOTOCATALYSTS

Titanium(IV) oxide samples were prepared by two techniques, namely, ultrasonic nebulization and flame hydrolysis, and the ultrasonic nebulization and furnace pyrolysis. Titanium(IV) chloride and diisopropoxy-titanium(IV)-bis-(acetylacetonate) were employed for the preparation of titanium(IV) oxide samples. The photocatalytic activities of the prepared samples were evaluated by measuring the degradation of 1,4-dichlorobenzene and compared with that of Degussa P25 titanium(IV) oxide. The ultrasonic nebulization and flame hydrolysis method was more efficient than nebulization and furnace pyrolysis. Products obtained using this method gave photocatalytic activities similar to that of P25.
