Abstract
Novel porphyrin/ZnO composites are prepared by using newly synthesized porphyrin-naphthalimide pentamer and its metal complexes as sensitizer. The obtained porphyrin/ZnO photocatalysts are characterized by scanning electronic microscopy (SEM), X-ray diffraction (XRD) FT-IR, and UV-vis spectroscopy. The photocatalytic activities of these photocatalysts are investigated by testing the photocatalytic degradation of methyl orange in aqueous solution under the mercury lamp irradiation. The results indicate that the photodegradation of methyl orange is significantly enhanced in the presence of 1-ZnO, 1a-ZnO and1 b-ZnO. Compared with bare ZnO, the 1-ZnO exhibites the best photocatalytic activity whereas 1c-ZnO, 1d-ZnO and 1e-ZnO exhibite poorer photocatalytic performance than the bare ZnO.
