| Abstract: | Three novel porphyrins, 5,10,15-tri-phenyl-20-4-(3-phenoxy)-propoxy]phenyl porphyrin, 5,15-di-phenyl-10,20-di-4-(3-phenoxy)-propoxy]phenyl porphyrin and 5-phenyl-10,15,20-tri- 4-(3-phenoxy)-propoxy]phenyl porphyrin, and their corresponding copper(II) complexes were synthesized and characterized spectroscopically. The photocatalytic effects of TiO2 samples impregnated with copper(II) porphyrins was investigated by photodegradation of 4-nitrophenol (4-NP) in aqueous solution under visible light. The photocatalysts were characterized by means of scanning electron microscopy (SEM), X-ray diffraction (XRD), UV-vis spectra and FT-IR spectra. The results indicated that CuPps were successfully loaded and interacted with the surface of TiO2 microsphere, which is crucial to enhance the activity of the catalytic composite under visible light. |
