Abstract

A modest sol-gel method has been employed to prepare the pure and Ag doped MnO₂ nanoparticles and methodologically studied their physical, morphological, and photosensitive properties through XRD, TEM, EDAX, Raman, UV, PL and N₂ adsorption - desorption study. Tetragonal crystalline arrangement with spherical nanoparticles was found out through XRD and TEM studies. The EDAX studies further supported that formation Ag in the MnO₂ crystal matrix. The bandgap energy of Ag doped MnO₂ was absorbed through UV spectra. Photo -generated recombination process and surface related defects were further recognized by PL spectra. Through visible light irradiation, the photo - degradation of methyl orange (MO) and phenol dye solutions were observed. The optimum condition of (10 wt% of Ag) Ag doped MnO₂ catalyst showed tremendous photocatalytic efficiency towards MO than phenol under same experimental study.

Keywords: Ag doped MnO(2); Electron-hole separation; Methyl orange; Photo-degradation; Sol-gel; Visible light.
