Preparation of Metal Phthalocyanine Supported on Polyvinyl Alcohol Nanofibers and Analysis of Its Dye Degradation Properties

Metal phthalocyanine, a synthetic porphyrin-like compound, has several applications in catalysis. Supported metal phthalocyanine catalysts have attracted increasing attention. In this study, glutaraldehyde (GA) was used for modifying polyvinyl alcohol (PVA) nanofibers by acetalization to improve the water resistance. Subsequently, cobalt tetra (2,4-dichloro-1,3,5-triazine) aminophthalo-cyanine (Co-TDTAPc) prepared and reacted with OH groups on surface of PVA produce Co-TDTAPc–PVA nanofibers. The resistance test results show that GA-treated demonstrate no significant change fiber appearance after being soaked 24 h, thus indicating excellent Moreover, considerably accelerate degradation azo fluorescent peach red hydrogen peroxide aqueous solution system, rate exceeds 98% 60 min. Furthermore, maintain high catalytic activity five cycles tiontesting. These findings indicate modified as navel supported catalyst potential application dye wastewater treatment.
