Abstract
Sonophotocatalytic reaction is a photocatalytic reaction with ultrasonic ir radiation or the simultaneous irradiation of ultrasound and light with a ph otocatalyst. The possibility of the effect of hybrid of sonochemical and ph otocatalytic reactions was examined. Liquid water was hardly decomposed to H-2 and O-2 by photocatalysis or sonolysis, independently. In order to deco mpose water, powdered TiO2 photocatalyst suspended in distilled water shoul d be simultaneously irradiated by light and ultrasound. This sonophotocatal ytic reaction was effective on the decomposition of water to H-2 and O-2. ( C) 2001 Elsevier Science B.V. All rights reserved.
