Abstract

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.

利用Fe3O4.MnO2高效去除染料二氧化硅纳米复合材料光催化臭氧氧化优化研究

在本研究中，Fe3O4.MnO2。首次制备了二硫化钼纳米催化剂，并将其应用于光催化臭氧氧化(PCO)工艺。考察了该三元异质结构纳米复合材料对100 mg酸性蓝113 (AB113)染料的去除效果。利用响应面法(RSM)测定L−1浓度。最佳工艺条件为pH = 3，纳米催化剂用量为2 mg，纳米催化剂用量为300 mg。在最佳条件下，L−1臭氧投加量超过20 min, AB113的去除率高达99%。此外，通过对实际纺织废水样品的处理，考察了合成催化剂在PCO工艺中的性能。由于两种氧化系统之间的协同作用，PCO已被发现比单独的光催化和催化臭氧化方法更有效。结果表明:Fe3O4.MnO2。二硫化钼可作为PCO工艺的高效催化剂。
