摘　　要：合成了3种外围带有不同基团(甲氧苯基、羟苯基、烟酸酰氧苯基)的卟啉衍生物,并分别用3种不同金属离子(Cu^(2+)、Zn^(2+)、Fe^(3+))对它们进行金属化,考察了这9种金属卟啉对水溶液中4-硝基苯酚(4-NP)的光催化降解活性。结果表明,光催化降解活性由外围基团和中心金属离子共同决定,外围基团为烟酸酰氧苯基、中心金属离子为Fe^(3+)的金属卟啉(FeTNPP)的光催化降解活性最高;以H_2O_2作氧化剂,光照4h4-NP即可被完全降解。In this paper,three porphyrin derivatives with different peripheral ligands（methoxyphenyl,hydroxyphenyl,and nicotinoyloxyphenyl）were synthesized,as well as metalized over three different metal ions（Cu^（2＋）,Zn^（2＋）,or Fe^（3＋））respectively.The photocatalytic degradation activities of these nine metalloporphyrins for4-nitrophenal（4-NP）in aqueous solution were investigated.The results showed that,the photocatalytic degradation activity was up to both peripheral ligand and metal centre of metalloporphyrin.Metalloporphyrin with nicotinoyloxyphenyl and Fe^（3＋）（FeTNPP）exhibited the highest photocatalytic degradation activity.4-NP could be degraded completely by FeTNPP under illumination for 4hwith H_2O_2 as an oxidant.
