| 摘 要： | 利用新合成的新型萘酰亚胺功能化的卟啉及其金属配合物敏化低温水热法制备的氧化锌（ZnO）纳米棒,制备了卟啉敏化ZnO的复合样品,利用SEM、XRD、FT-IR、UV-vis吸收光谱对复合材料的结构和形貌进行了表征.在汞灯照射下,利用该卟啉/ZnO复合样品进行了光催化降解甲基橙研究.实验结果表明,与未复合的ZnO相比,用自由基卟啉1、锌卟啉1a和铜卟啉1b敏化的复合样品的光催化活性得到显著提高,其中自由基卟啉1的复合材料表现出了最佳的催化效果.而锰卟啉1c、铁卟啉1d钴卟啉1e敏化样品的催化活性相比纯ZnO有了不同程度的下降.

| 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 1 c-ZnO,1 d-ZnO and 1 e-ZnO exhibite poorer photocatalytic performance than the bare ZnO. |
