Photocatalytical Treatment of Synthetic Wastewater Containing Chlorophenols by TiO2 Nanoparticles Sensitized with Cobalt Phthalocyanine Under Visible Light

Journal Title: Journal of Chemical Engineering & Process Technology - Year 2017, Vol 8, Issue 2

Abstract

In this paper, sensitization TiO2 nanoparticles with sulphonated cobalt phthalocyanine(CoPcS-TNP) has been reported. The prepared samples characterized by different analysis such as: XRD, FT-IR, EDX, nitrogen physisorption, TG and TEM techniques. The XRD, TEM and nitrogen physisorption results showed the prepared samples containing only the pure anatase phase with crystal sizes in the range of 7-10 nm and high surface areas of 133-280 m2/g. The presence of CoPcS in photocatalysts confirmed by FT-IR and EDX analysis. The CoPcS-TNP samples showed efficient activity for photocatalytic degradation of 4-chlorophenol (4-CP) and 2,4-dichlorophenol (2,4-DCP) under visible light. The sample CoPcS-TNP (2.24) was the best photocatalyst for degradation of chlorophenols under visible light. The degradation reactions follow first-order kinetics. Reusing experiments of the photocatalyst showed a reduction activity from 95% to 60% for chlorophenols degradation after four cycles. The major intermediates of degradation were oxalic acid, pyruvic acid and malonic acid which identified by gas chromatography-mass spectrometry (GC/MS).
