Abstract
In this work, preparation and visible light induced photocatalytic activity of sulphonated cobalt phthalocyanine complex sensitized TiO2 nanoparticles (CoPcS-TNP) as photocatalyst for photocatalytic degradation of 4-chlorophenol (4-CP) has been reported. The study carried out using XRD, DRS, FT-IR, nitrogen physisorption and TEM techniques. Results revealed that TiO2 nanoparticles possessed only the anatase phase with crystal sizes of about 7-10nm. The doping amount of CoPcS remarkably affected the activity of TiO2 nanoparticles as photocatalyst. Oxalic acid, pyruvic acid and malonic acid were the major intermediate species at the final stage of the degradation process as identified by gas chromatography-mass spectrometery.
