Structural, optical and photocatatic activity of Ag doped ZnO nanoparticles obtained by sol-gel method

Pure and Ag doped ZnO-NPs were synthesized through a facile Sol-Gel methods. The structural, morphological and photocalaytic activity of the nanoparticles were studied with respect to pure and Ag doped ZnO nanoparticles. XRD result is monodyspersed hexagonal wurtzite structure with an average crystallite size varied from 3.20 to 2.06nm. The TEM images showed ZnO-NPs with spherical shapes, the Raman spectra measurements indicated that the pure and Ag doped ZnO-NPs had a high crystalline quality. The performance and stability of the Ag doped ZnO-NPs, for the photocatalytic degradation of Methylene Blue under sun light irradiation evaluated.
