Transparent anatase TiO2 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 TiO2 thin film, whereas only degradative reaction took place in a P25 coated film existed.
