Abstract
The MoS2-ZnFe2O4 composite catalyst was fabricated by a hydrothermal method and applied to decompose tetracycline (TC) by activating persulfate (PS) with the assistance of visible light (Vis). The TC elimination efficiency of MoS2-ZnFe2O4 catalyst reached 84.5% within 30 min, which was much higher than that of either MoS2 or ZnFe2O4 alone and this catalyst demonstrated satisfactory catalytic performance over a wide pH range (3–9) for the removal of TC. The improved efficiency of TC degradation can be attributed to the production of highly active free radicals such as •OH, SO4•-, and O2•-. In addition, the catalyst showed favorable stability and recyclability when tested in three consecutive cycles.
