| 中文摘要: |
| 综述了光催化降解有机污染物和杀菌的机理，其中降解有机物机理的主要内容为空穴和羟基自由基(.OH)氧化分解有机污染物，杀菌机理与降解有机物类似，即电子和空穴或含氧自由基攻击细菌的细胞壁、细胞膜和胞内成分，使细菌失活。分别从Fe2+和Cu2+两种离子介导的Fenton反应总结了Fenton反应的机理，得出两种离子介导的Fenton反应具有类似机理的结论。最后阐述了目前在光催化体系中引入Fenton反应的研究现状及作用机理，发现将Fenton反应引入光催化体系是促进光催化活性的有效途径。 |
| 英文摘要: |
| This paper reviewed the mechanism of photocatalytic degradation of organic pollutants and sterilization, among them the main content of organic matter degradation mechanism were holes and hydroxyl radical (OH) oxidative decomposition of organic pollutants, the sterilization mechanism and degradation of organic matter, namely electrons and holes or oxygen free radicals attack bacteria cell wall, cell membrane and intracellular constituents, the bacterial inactivation. The mechanism of Fenton reaction was summarized from Fe2+ and Cu2+ ion-mediated Fenton reactions respectively, and the conclusion that the two ion-mediated Fenton reactions had similar mechanisms was drawn. Finally, the current research status and mechanism of introducing Fenton reaction into photocatalytic system were described, and it was found that introducing Fenton reaction into photocatalytic system was an effective way to promote photocatalytic activity. |
