Abstract

The present work reports the photodegradation results of the Reactive Black 5 (RB5) izo dye by using titanium oxide films as photocatalysts. The films were obtained by ultrasonic spray pyrolysis deposit technique from a 0.0076 M of Ti(IV)-acetyl-acetonate and N, Ndimethylformamide solution over corning glasses as substrates. The film obtained by deposition at 450 °C for 6.0 min shows the best photocatalysis behavior, which may degrade 50% of 100 ppm RB5 in a period of 120 min, as monitored with a spectra-photometer UV-Vis between 190 to 900 nm. After 180 minutes of degradation, a 70% conversion could be obtained. These results are better than that obtained with TiO2 powders as photocatalyst.
