COMPARISON OF PHOTOREACTIONS OF RHODAMINE B CATALYZED BY A TiO2 THIN FILM AND A DEGUSSA P-25 COATED FILM

doi:10.7517/j.issn.1674-0475.1998.02.117

Abstract

Abstract: Transparent anatase TiO₂ thin film was prepared on glass substrates by dip coating method. The photocatalytic properties of the film was assessed by measuring the photodegradative oxidation of Rhodamine B in aqueous solution and compared with a Degussa P-25 coated film. This film showed much higher photoactivity than P-25 coated film initially because the photoreactive mechanisms assisted by the two kinds of films are obviously different: fast N-de-ethylation and further degradation accompanied the degradation of Rhodamine B catalyzed by a TiO₂ thin film, whereas only degradative reaction took place in a P-25 coated film existed.

Key words: TiO₂ thin film, Rhodamine B, photodegradation
