英文摘要This article explores a supported catalyst of Fe(bpy)(3)(2+) on a cationic exchange resin (Amberlite IRA 200) as a photocatalyst for the degradation of organic pollutants by activating molecular oxygen under visible irradiation (lambda > 420 nm) in water. Different from Fe(bpy)(3)(2+) which is not photoactive in solution, the supported catalyst exhibits a very efficient photoactivity for the degradation of N,N-dimethylaniline and the cationic dyes of Rhodamine B (RhB) and Malachite Green (MG) in an aerated aqueous medium. TOC removal yield was 75, 60 and 58%, respectively, after 700 min of visible light irradiation. The photocatalytic activity of the supported Fe(bpy)(3)(2+) remained unchanged after 22 cycles of over 100 h. The photocatalyst was characterized by UV-Vis diffuse reflectance, and X-ray photoelectron spectroscopies (XPS). EPR studies suggest that the active superoxide species {Fe(bpy)(3)(3+) O-2(.-)} are involved in the light-activated reaction. A reaction mechanism is proposed in the text. (C) 2003 Elsevier B.V.
