Preparation of Ag-MOF/BiOBr as High-Performance Photocatalyst for Degradation of Crystal Violet Dye from Aqueous Solution

In the present research, Ag-MOF/BiOBr nanoparticles was synthesized and studied as a photocatalyst for degradation of crystal violet (CV) dye. In addition, the synthesized photocatalyst was characterized by FT-IR analysis. The photocatalytic performance of this photocatalyst was investigated for degradation of CV dye by visible light irritation. The effects of variables such as CV dye concentration, photocatalyst amount, pH, and irradiation time on crystal violet dye degradation efficiency was studied by central composite design with response surface methodology. The optimum conditions for CV dye degradation were obtained by ۹.۹ mg Ag-MOF/BiOBr photocatalyst, and ۵.۷ μg/mL crystal violet solution with pH = ۴, at ۴۶.۴۶ min and maximum degradation of CV dye was ۹۹.۲% at the optimum conditions.
