The Fenton reaction is restricted by the sluggish Fe(II)/Fe(III) cycle and low activation efficiency of oxidants. Herein, 1T/2H MoS2 nanoflowers with abundant defects a multiphase structure, loaded on carbon felts (denoted as THMC), have been prepared to boost catalytic activity in Fenton-like oxidation. ultrathin nanosheets promote adsorption iron ions pollutants, while unsaturated S atoms exposed Mo(IV) sites facilitate conversion Fe(III) Fe(II). Additionally, 1T phase accelerates electron transfer cycling, thereby synergistically enhancing oxidation improving pollutant elimination. Moreover, loading not only overcomes limitations powder separation recycling but also offers robust stability for long-term applications. Thanks these structural characteristics, degradation efficiencies rhodamine B bisphenol A THMC cocatalyzed system reach 99.3% 98.1%, respectively, corresponding rate constants (kobs) are 10.3 10.1 times higher than those traditional Fe2+-catalyzed system. Impressively, still maintains excellent cocatalytic performance after 5 cycles exhibits high across wide pH ranges. can efficiently eliminate variety organic pollutants adapt natural water samples. Furthermore, several varied structures ratios has investigated probe effect structure. Interestingly, kobs value 52.4% was 5.9 3.4 that 5.6%-1T RhB BPA, respectively. could be further improved an increase 66.6%. These observations reveal significant role effects AOPs.
