Solid-phase photocatalytic degradation of polystyrene with TiO2 modified by iron (II) phthalocyanine

High photocatalytic degradation activity of the polyvinyl chloride (PVC)–vitamin C (VC)–TiO2 nano-composite film

“…To eliminate these drawbacks, many attempts have been carried out to modify TiO 2 characteristics by surface modifiers through three ways: (a) by inhibiting charge recombination; (b) by expanding the wavelength response range; and (c) by changing the selectivity or yield of a particular product [21]. Recent studies indicate that the surface modification of TiO 2 by metallophthalocyanine shows a high photocatalytic activity for degradation of polymers [22][23][24]. Vitamin C (VC), a naturally available compound, has been used as a modifier in a solid-state cell based on TiO 2 and CuI, where the photo-excited dye molecules inject electrons into the conduction band of TiO 2 and holes into the valence band of CuI.…”

Solid-phase photocatalytic degradation of polyethylene–goethite composite film under UV-light irradiation

“…Soild-phase photocatalytic degradation of polymers such as PVC or even chlorine-less polymer such as polyethylene (PE) has attracted intense interest in recent years [11][12][13][14][15][16]. A few recent reports [11][12][13][14] describe the use of TiO 2 as the photocatalyst for oxidative degradation of PE.…”

Photodegradation activity of polyvinyl chloride (PVC)–perchlorinated iron (II) phthalocyanine (FePcCl16) composite film

“…Photosensitized degradation of persistent organic pollutants (such as chlorophenol [10][11][12][13][14][15], 2,4-dichlorophenoxyacetic acid [16], atrazine [17], bisphenol A [18], organic sulfides [19] and organic dyes [20,21]) by different metallophthalocyanines in homogeneous or heterogeneous system have already been examined. To our best knowledge, there are only few reports on the photodegradation of polymer with metallophthalocyanines modified TiO 2 [22][23][24], while there is no research in the field of the photodegradable plastic with metallophthalocyanine directly. Composition of plastic with metallophthalocyanine represents a new way to degrade waste plastic in an open air.…”
