SYNTHESIS AND STRUCTURAL PROPERTIES OF ZnO NANOPARTICLES BY ALTERNANTHERA SESSILE LEAVES EXTRACT.

Green synthesis is environmentally friendly technique for synthesis of metal Oxide nanoparticles.In this present work, synthesis of ZnO nanoparticles were prepared by Green Synthesis method. Here Leaf extract of Alternanthera Sessile can be used as reducing and capping agent for synthesis of stabilized ZnO nanoparticles .ZnO nanoparticles were characterized by X- ray diffraction (XRD), Scanning Electron Microscope (SEM), Energy dispersive analysis of X-rays (EDAX)and Fourier transform infrared spectroscopy (FTIR).From X-ray diffraction studies it is observed that (101) phase obtained at 36.680 2theta value.The size of the nanoparticle is 22nm at this peak.It was observed that the shape of the ZnO particles is agglomerated spherical by SEM attached with EDS analysis. From FTIR analysis ,it was observed that Alkenes and Nitriles functional groups in this leaf extract used as reducing agent for synthesis of ZnO nanoparticles. It was proved by peaks were obtained at wave numbers 809cm-1 ,909cm-1,2331cm-1 and 2361cm-1.
