AbstractIn this paper, MnPcTc (2, 9, 16, 32-tetracarboxylic phthalocyanine manganese) was immobilized on a WO3 support and prepared using the method of in-situ synthesis. UV-visible diffuse reflectance spectra (UV-Vis DRS) was employed to characterize the immobilized catalyst. Under visible light irradiation (lambda >= 450 nm), the photocatalytic degradation of the organic dye rhodamine B (RhB) and the small, stable molecular organic substance, 2, 4-dichlorophenol (2, 4-DCP) were used as probe reactions. Complete decolorization of RhB and 55.35% degradation of 2, 4-DCP occurred after 300 min of irradiation. By following the concentration change of reactive oxygen species it was demonstrated that the oxidation process was dominated by the hydroxyl radical (center dot OH) generated in the system.
