Semiconductor-assisted Photodegradation of Dye and Pesticide by ZnO:Ru and ZnO/RuO 2 /AgO Nanocomposites, Synthesised by Electrolytic method (original) (raw)
ZnO:Ru(III) and ZnO/RuO 2 /AgO nanocomposites were synthesized by electrolytic method. The synthesized composites were examined for their catalytic properties towards photodegradation of organic contaminants. ZnO:Ru(III) and ZnO/RuO 2 /AgO nanocomposites were characterized by UV-Visible spectroscopy, Infrared spectroscopy, Scanning electron microscopy and X-ray diffraction datas. The size and crystal strain was calculated using Williamson-Hall plot. The photodegradation activities of ZnO:Ru(III) and ZnO/RuO 2 /AgO nanocomposites were evaluated with fast green dye and parathion pesticide. The comparison of degradation of dye and pesticide using ZnO and synthesized ZnO:Ru(III) and ZnO/RuO 2 /AgO composites revealed the high efficiency of the title compounds. The observed decrease in chemical oxygen demand (COD) value of the treated pesticide and dye showed destruction of organic molecules along with color removal.
