A facile green approach of Fe2O3, Fe2O3 @Ag, Fe2O3 @AC and Fe2O3 @Ag@AC NPs synthesized via Cocos nucifera L for waste water treatment applications

Abstract

In this current work simple one-pot green synthesis approach was applied for synthesis of Fe2O3, Fe2O3@Ag, Fe2O3@AC and the Fe2O3@Ag@AC Nanocomposites (NCs) using Cocos nucifera L. The Cocos nucifera L extract acts both as reducing agent as well as capping agent. Through XRD of green synthesized samples, it was determined that the material had a cubic structure with a maximum absorption at 373 nm assigned to the band-gap. According to the XRD study, the average grain size was 29–30 nm. As a result of FESEM and TEM analysis, rod-like nanostructures were observed with reductions in size. In comparison with methylene blue dye, the synthesized Fe2O3, Fe2O3@Ag, Fe2O3@AC and the Fe2O3@Ag@AC NCs displayed excellent photocatalytic activity. The reason is that charcoal has an adsorption property and iron oxide has a heavy metal reducing property. These properties of the synthesised nano composite allow it to be used in water treatment facilities, and dye effluent removal systems.
