Abstract

Nowadays water pollution is a major problem in the world threatening human health and ecosystems. Nanocomposites (NCs), as a very large group of promising nanomaterials, demonstrate high performance in the water treatment process. In this paper, the green synthesis of zinc oxide (ZnO)-NPs stabilized on eggshell (ES) powder particles by Ferulago macrocarpa (F. macrocarpa) extract, as a new natural reducing agent, was considered to produce ZnO/ES-NCs. Different characterization techniques such as SEM, TEM, EDS, XRD, and IR were used for the characterization of the nanocomposites. The results confirmed the synthesis of pure ZnO-NPs with an average particle size of 25 nm, uniformly stabilized on the ES matrix. Further, this structure was a promising material for photocatalytic degradation of diazinon with high antibacterial efficiency against fish and human bacterial pathogens and could be employed as an eco-friendly product for disinfection in aqueous media.
