In this work, a flower-like MnFe2O4-MoS2 (FMW) catalyst was successfully prepared as a catalyst for photo-Fenton oxidation. The flower-like structured FMW possessed large open surface area, which exposed enough active sites and can fully contact with tetracycline (TC). We studied the effect of different FMW composites, H2O2 concentration and light intensity on the photo-Fenton process. 1FMW (MnFe2O4 : MoS2 = 1:10 in mol) exhibited the best degradation effect on TC, and 1 mmol/L of H2O2 and 398.73 mW/cm(2) of light were the optimum parameters. A p-n heterojunction was formed in 1FMW, ensuring t...
