Sono-Hydrothermal Design of Plasmonic Disilver Dimolybdate Nanophotocatalyst:Excellent Removal of Acid Orange ۷

Herein, the visible-light-active plasmonic disilver dimolybdate (Ag۲Mo۲O۷) nanophotocatalyst with suitable-band gap was synthesized by a sono-hydrothermal method to degrade the ۲۵ mg/L acid orang ۷ (AO۷) in the solar spectrum range. The mentioned nanophotocatalyst was characterized by X-ray diffraction (XRD) and field emission scanning electron microscopy (FESEM) analyses. The result obtained from XRD exhibited that the mentioned sample fabricated successfully and has the high purity. The FESEM image of Ag۲Mo۲O۷ showed the microrod morphology. Moreover, the outcomes of reactors test showed the degradation percentage of AO۷ over the plasmonic Ag۲Mo ۲O۷ was about ۹۸% with ۱ g/L catalyst and after ۱۸۰ min simulated sunlight irradiation. The highly activity of plasmonic Ag۲Mo۲O۷ could be dedicated to the suitable band gap, high activity in the solar light region, which would lead to the increase of excitons (electron-hole pairs) and the plasmonic effects of Ag particles
