Efficient Dye Removal Using Fe3O4.MnO2.MoS2 Nanocomposite in Optimized Photocatalytic Ozonation Process
ABSTRACT In this study, Fe3O4.MnO2.MoS2 nanocatalyst has been fabricated for the first time and applied in the photocatalytic ozonation (PCO) process. The efficiency of this ternary heterostructure nanocomposite was evaluated in the removal of Acid Blue 113 (AB113) dye with 100 mg.L−1 concentration utilizing response surface methodology (RSM). The optimal condition of the process was attained at pH = 3, using 2 mg of the nanocatalyst and 300 mg.L−1 ozone dosage applied over 20 min. High efficiency of AB113 removal (99%) was observed at the optimal condition. In addition, the performance of the synthesized catalyst in the PCO process was investigated in the treatment of a real textile effluent sample. The PCO has been found to be more efficient than the individual photocatalysis and catalytic ozonation methods due to the synergistic effect between the two oxidation systems. The results proved that Fe3O4.MnO2.MoS2 can be used as a highly efficient catalyst in the PCO process.
