Abstract
In the present work, a facile hydrothermal route was employed to synthesize the nanocomposite MgFe2O4/MoS2, which acted as a heterogeneous photo-Fenton catalyst for the degradation of a synthetic diazo dye, Acid Blue 113 (AB113). The nanocatalyst produced underwent analysis using multiple characterization techniques. The parameters influencing the oxidative reaction were statistically modeled and optimized using response surface methodology. Optimal degradation efficiency for AB113 (94.92%) was attained at pH 8.79 using 10 mg of MgFe2O4/MoS2 nanocatalyst, 1.6 mL of H2O2, and a reaction duration of 27 min. The synergistic effect resulting from the formation of electron-hole pairs renders the combined photocatalysis and Fenton process a more efficient treatment approach. The kinetic study data indicate that the photo-Fenton process follows the pseudo-first-order model. The nanocatalyst fabricated demonstrated exceptional stability, maintaining a high degradation performance after seven consecutive photo-Fenton cycles. The results obtained indicate that the MgFe2O4.MoS2/H2O2/Vis system is an effective method for treating wastewaters containing organic contaminants.
