Fenton's reagent is a solution of hydrogen peroxide (H2O2) with ferrous iron (typically iron(II) sulfate, FeSO4) as a catalyst that is used to oxidize contaminants or waste waters as part of an advanced oxidation process. Fenton's reagent can be used to destroy organic compounds such as trichloroethylene (TCE) and tetrachloroethylene (perchloroethylene, PCE). It was developed in the 1890s by Henry John Horstman Fenton as an analytical reagent. WebSep 9, 2024 · We here report a new approach to activate H 2 O 2 in a co-catalytic Fenton system with oxygen incorporated MoS 2, namely MoS 2−x O x nanosheets. The MoS 2−x O x nanosheets assisted co-catalytic Fenton system exhibited superior degradation activity of emerging antibiotic contaminants (e.g., sulfamethoxazole).

WebJan 1, 2008 · During the Fenton reaction, ferrous ions can quickly react with H 2 O 2 to produce hydroxyl radicals and ferric ions ( k = 70 M −1 s −1) [6], which will then be reduced by the dye to ferrous ions again. Meanwhile, ferric ions can also react with H 2 O 2, producing hydroperoxide radicals which cause a second decomposition process for the dye.
