چکیده:

In this work we synthesized TiO2-based photocatalyst containing cobalt phthalocyanine tetrasulfonate (CoPcTs) by hydrothermal synthesis method. The resulting photocatalyst was characterized by X-ray powder diffraction, BET, FT-IR and DR-UV-vis spectroscopy. Photocatalyticoxidation of 2,4-dichlorophenol (2,4-DCP) was performed by this catalyst in presence of low amount of H2O2 as an auxiliary oxidant under ambient condition. The UV-vis spectrophotometeric method was used for monitoring the degradation process. This photocatalyst displays an efficient photoactivity for degradation and mineralization of 2,4-DCP. The photocatalytic oxidation process was completed within 150 min using a dose of 0.2g/L of the catalyst.
