The photocatalytic activity of polycrystalline TiO2samples impregnated with dendritic zinc phthalocaynine was investigated using the rhodamine B (RhB) aqueous solution as a probe. The morphology and structure of TiO2/dendrimer phthalocyanine nanocomposite catalyst were characterized by X-ray diffraction (XRD) and UV-Vis spectra. Significant activity improvements of the TiO2/dendrimer phthalocyanine nanocomposite photocatalyst were observed possible in terms of lower loading amount, enhanced photo-reactivity under light irradiation, as well as chemical, and photochemical stability of the sensitizers.
