In this study, the effects of disperse blue dye-sensitization on the photocatalytic properties of the Ag-N co-doped TiO2 nanoparticles loaded on polyethylene terephthalate (PET) filaments are investigated under visible light irradiation. The microstructure and photocatalytic properties of the as-synthesized TiO2 nanocomposites, as well as the as-prepared PET filaments, are systematically characterized. The photocatalytic performance of the PET filaments coated with the Ag-N co-doped TiO2 nanoparticles sensitized with disperse blue dyes is evaluated via its capacity of photo-degrading methyl orange (MO) dyes under visible light irradiation. It is found that the holes are the predominant reactive radical species and the hydroxyl and superoxide radicals play a subordinate role in the photocatalytic reaction process. The reaction rate constant of the photocatalytic composite filaments is nearly 4.0 times higher than that of the PET filaments loaded solely with TiO2 nanoparticles. The resultant photocatalytic composite filaments are evident to be capable of repeatedly photo-degrading MO dyes without losing its photocatalytic activity significantly.

A series of binuclear metal (II) phthalocyanine hexasulphonates, (M-M)Pc, including (Co-Co)Pc, (Co-Zn)Pc, (Co-Mn)Pc, (Zn-Zn)Pc, (Zn-Mn)Pc and (Mn-Mn)Pc were synthesized and immobilized on nanocrystalline TiO2 thin films. The nanocrystalline TiO2 thin film was characterized by SEM, XRD and profilometer. The catalytic activity of various (M-M)Pc/nanocrystalline TiO2 thin films was evaluated by the degradation of methylene blue (MB) with air as the oxidant under visible light irradiation and dark condition. The results indicated that the prepared nanocrystalline TiO2 thin film had good crystalline and uniform particle size distribution. According to the degradation results of MB, various homo/hetero (M-M)Pc can sensitize nanocrystalline TiO2 thin films and improve their photocatalytic activity under visible light irradiation. The catalytic activity of hetero (M-M)Pc/nanocrystalline TiO2 thin films were more effective than that of homo (M-M)Pc under both visible light irradiation and dark condition, and the air purging was essential in degradation of MB. Therefore, these (M-M)Pc/nanocrystalline TiO2 thin films can be applied to the degradation of MB as a promising catalyzer.
