Dye sensitized semiconductor can constitute efficient photochemical systems for the environmental remediation. Using metal free phthalocyanines (H2Pc) and metallophthalocyanine (MPc) complexes, has attracted much interest owing to its high stability, visible light photosensitivity and catalytic properties. Phthalocyanine sensitized titaniumdioxide (Pc/TiO2) catalyst is able to achieve the degradation of many organic pollutants by visible light as energy and O2 in the air as the oxidant under ambient conditions. Owing to above mentioned properties, H2Pc and MPc immobilized TiO2 photocatalysts have been tested for photocatalytic removal of organic and inorganic pollutants. In this review, production, characterization and application of Pc/TiO2 catalysts are described and particularly focused on the studies concerning the photocatalytic applications either in the form of nano dust for suspension applications or thin film. Pollutants were classified into two main groups; namely organic toxic pollutants and dyes.
