Green biosynthesis of zinc oxide nanoparticles via aqueous extract of cottonseed

Green synthesis of nano-particles by using of aqueous extract of cottonseed as antioxidant materials is an efficient method along with advantages such as economically, simplicity of work-up process and eco-friendly approaches. Also, this study was focused on synthesis of ZnO nanoparticles (ZnO-NPs) with using an aqueous extract of cottonseed. The synthesized ZnO-NPs were characterized by using XRD, EDX, SEM, FTIR and UV-VIS spectroscopy. By the collected results, especially from Fourier transform infrared spectroscopy (FTIR) data was concluded the presence of heterocyclic, aromatic and phenolic compounds in water extract of plant are acts as antioxidants for nano-particle synthesis. In other side, the SEM pattern analysis was showed that ZnO-NPs have a crystalline wurtzite phase. Finally the XRD spectrum identified the average particle size of ZnO NPs about 18.97 nm.
