金属卟啉衍生物催化降解污染物研究进展
The degradation of pollutants catalyzed by metalloporphyrin derivatives
【摘要】 由于工业化和城市化的快速发展而带来的环境问题已经引起了人们的广泛关注.土壤和地下水中不断排放的持久性污染物,对人们的健康造成了极大的威胁,因此需要更加有效的策略来解决.卟啉类物质由于具有特殊的氧化还原性质和光敏性,已经被广泛用于有机污染物的去除.本文总结了金属卟啉的最新研究进展,对其在类芬顿和光催化领域的应用进行了详细的介绍,并且讨论了高价铁氧卟啉物种,单重态氧和超氧自由基的产生机理.最后,指出了现有研究的不足以及未来的发展方向.
【Abstract】 The recent growing threat of environment and energy crisis have aroused increasing concern due to the rapid development of industrialization and urbanization. The aggravating release of recalcitrant pollutants in water and soil poses great threat to human health, demanding for more efficient strategies to address the environmental issue. Considering the photosensitiveness and redox properties of metalloporphyrins in nature, porphyrin-based chemistry has reached an unprecedented period of rapid development for the application of pollution abatement. This review summarized recent advances of porphyrins chemistry, highlighted Fenton-like redox chemistry and photo-excitability of porphyrins. The generation of high-valent iron oxo porphyrin species, 1O2 and O■ were also discussed. Finally, challenges in current research were identified and perspectives for future development in this area were presented.
