| Abstract: |
| 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. |
