Abstract
Mn, Zr co-doped Ag2O nanoparticles (NPs) were blended through a wet chemical strategy, and the physicochemical properties of doped and co-doped silver oxide nanoparticles were characterized using X-ray diffraction, UV-DRS visible spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy with energy dispersive X-ray spectroscopy, high-resolution transmission electron microscopy, Brunauer–Emmett–Teller (BET) and electrochemical impedance spectroscopy (EIS) and photoluminescence techniques. XRD reveals that the crystal structure of Mn, Zr co-doped Ag2O NPs has a face-centered cubic phase (FCC). Photoluminescent spectra analysis further demonstrates that the Mn, Zr co-doped Ag2O extraordinarily improves the charge generation and suppresses the charge recombination of photogenerated electron–hole pairs, which would be advantageous to improving the photocatalytic properties. The photocatalytic properties of Mn, Zr co-doped Ag2O NPs were assessed by the degradation of rose bengal dye under visible light illumination. The results revealed that Mn, Zr co-doped Ag2O (Mn, Zr–Ag2O) showed greater photocatalytic activity compared with different photocatalysts. In addition, Mn, Zr co-doped Ag2O was seen as a reusable photocatalyst.
