ABSTRACT

Ag/ZnO nanoparticles have been prepared via simple thermal treatment of a hetero tri-nuclear precursor compound [Zn(Imdz)4(Ag(CN)2)2] (1) (Imdz = Imidazole) as precursors at 550 °C in air for 4 h. A variety of techniques such as UV-Vis spectroscopy, IR spectroscopy, XRPD, XPS, SEM, TEM and EDX were used for their characterization. These nanoparticles show optical band gap at 2.75 eV. Photocatalytic reactivity of these nanoparticles has been evaluated by studying the degradation of C. I. Reactive Yellow 84 (RY 84), a popular and widely used reactive dye in cotton industry.
