“…Mechanism of photodegradation of organic pollutions in presence of oxygen and porphyrin or phthalocyanines, either immobilized or in solution 31,32 or in solution, 33,34 may involve both type I (electron or atom transfer) and/or type II (singlet oxygen) processes. To test whether the mechanism of reactions of the systems in these studies involves electron transfer and/or singlet oxygen, photodegradation reactions were carried out in the presence and absence of oxygen.…”

Zinc tetraamino-phthalocyanine (ZnTAPc) supported by multi-walled carbon nanotubes (MWCNTs) hybrid materials were successfully fabricated by the method of chemical grafting and their photocatalysis behavior was reported. The as-prepared products were thoroughly characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectroscopy, transmission electron microscopy (TEM), UV-vis spectra, thermogravimetric analysis (TGA) and FT-IR spectra. The results showed that the ZnTAPc nanostructures were not only grown on the multi-walled carbon nanotubes but also uniformly distributed without aggregation. The photocatalytic studies revealed that the ZnTAPc-MWCNTs hybrid materials exhibited high absorption capacity and simultaneously excellent visible-light-driven photocatalytic performance for rhodamine B (RB) under visible-light irradiation. A possible mechanism for the photodegradation of rhodamine B (RB) was suggested. The hybrid materials provide great potential as active photocatalysts for degrading organic pollutions.

“…Mechanisms of sensitized photodegradation of pesticides in the presence of oxygen and porphyrin or phthalocyanines, either immobilized [18,20,33] or in solution [34][35][36][37], may involve both type I (electron or atom transfer) [18,20,34,36] and/or type II (singlet oxygen) [33,35,[37][38][39] processes. To test whether the mechanism of reactions of the systems in these studies involves electron transfer and/or singlet oxygen, photodegradation reactions were carried out in the presence and absence of oxygen and in the presence of sodium azide, used as a singlet oxygen quencher.…”

In the present study the authors investigated a set of three new zinc(II) phthalocyanines (zinc(II) tetranitrophthalocyanine (ZnTNPc), zinc(II) tetra(phenyloxy)phthalocyanine (ZnTPhOPc) and the tetraiodide salt of zinc(II)tetra(N,N,N-trimethylaminoethyloxy) phthalocyaninate (ZnTTMAEOPcI)) immobilized into Al-MCM-41 prepared via ship-in-a-bottle methodology. The samples were fully characterized by diffuse reflectance-UV-vis spectroscopy (DRS-UV-vis), luminescence, thermogravimetric analysis (TG/DSC), N(2) adsorption techniques and elemental analysis. A comparative study was made on the photocatalytic performance upon irradiation within the wavelength range 320-460nm of these three systems in the degradation of pesticides fenamiphos and pentachlorophenol. ZnTNPc@Al-MCM-41 and ZnTTMAEOPcI@Al-MCM-41 were found to be the most active systems, with the best performance observed with the immobilized cationic phthalocyanine, ZnTTMAEOPcI@Al-MCM-41. This system showed high activity even after three photocatalytic cycles. LC-MS product characterization and mechanistic studies indicate that singlet oxygen ((1)O(2)), produced by excitation of these immobilized photosensitizers, is a key intermediate in the photocatalytic degradation of both pesticides.

A novel photodegradable TiO 2 -Fe(St) 3 -polystyrene (TiO 2 -Fe(St) 3 -PS) nanocomposite was prepared by embedding TiO 2 and Fe(St) 3 into the commercial polystyrene. Ferric stearate was added into polymer as cocatalyst in order to improve the dispersion in polystyrene and photocatalytic efficiency of TiO 2 nanoparticles. Solid-phase photocatalytic degradation of the TiO 2 -Fe(St) 3 -PS nanocomposite was carried out in an ambient air at room temperature under ultraviolet lamp. The properties of TiO 2 -Fe(St) 3 -PS composite film were compared with that of the pure PS film and the TiO 2 -PS composite film, through weight loss monitoring, scanning electron microscope, gel permeation chromatogram, and FTIR spectroscopy. The photodegradation efficiency of TiO 2 -Fe(St) 3 -PS composite film was higher than that of the pure PS film and the TiO 2 -PS composite film under the UV light irradiation. The average molecular weight (M w ) of TiO 2 -Fe(St) 3 -PS composite film decreased 63.08%, and the number of average molecular weight (M n ) decreased 79.49% after UV light irradiation for 480 h. Photo-oxidation leads to an increase in the low molecular weight fraction by chain scission, thereby facilitating biodegradation.
