Promising Solar-Light Driven Emerging Contaminant Degradation over Ag-Bi۲MoO۶ Nanosheets Photocatalyst

Herein, Bi۲MoO۶ nanophotocatalyst was synthesized via sono-solvothermal method and was decorated with Ag particles via photodeposition. Characterization of the Ag-decorated plasmonic Bi۲MoO۶ nanophotocatalyst was carried out by XRD and FESEM techniques. The XRD analysis confirmed the formation of the desired crystalline phase, and the FESEM analysis also showed Bi۲MoO۶ nanosheets-Ag particles morphology. The fabricated nanophotocatalyst was used in the degradation of the antibiotic ofloxacin under simulated solar light. The ۸۴.۵% degradation was achieved over the mentioned photocatalyst in the ۱۸۰ min irradiation light. This result is mainly devoted to the well crystallization, the presence of the ultrasound energy and the increase of the dispersion, which increased the number of available active sites, the efficient absorption of the sunlight, and decrease of electrons and holes recombination resulting from the surface plasmon resonance (SPR) property of Ag particles on the surface of nanosheets
