Abstract:

Based on the three synthesized porphyrin derivatives and their corresponding metallic complexes, the photocatalytic activity of anatase TiO2 samples impregnated with CuP were investigated by carrying out the photodegradation of 4-nitrophenol(4-NP) in aqueous suspension and under visible light. The photocatalysts were characterized by SEM, XRD and UV-Vis. The photocatalysts show good stability under irradiation conditions and they continued to maintain good photocatlytic activity also after several cycles.With increasing the substituents, the photocatalytic efficiency of CuP-TiO2 photocatalyst improved under visible light.
