Title : Synthesis and characterization of flower-like Zno nanoparticles by green routes
Abstract:
The synthesis of metal oxide semiconductor nanoparticles has attracted much attention in recent past. Nanoparticles are broadly used in solar energy conversion, catalysis, varistors, gas sensors, and non-linear optics, etc. Owing to the large band gap zinc oxide nanoparticles are widely used in numerous applications. Zinc oxide nanoparticles has a wide band gap of approximately 3.3 eV. In this paper, we have reported synthesis and characterization of flower like structures of ZnO nanoparticles synthesized by the green routes. In this zinc acetate dehydrate [Zn(CH3COO)2. 2H2O] and aqueous extract of Dahlia Pinnata leaves are used. Deionized water used as a solvent. The unique morphology of ZnO NPs flower like structures enhances its sensing properties in comparison to the spherical ones. The obtained ZnO nanoparticles are characterized by the UV-vis-nir spectroscopy, X- Ray diffraction (XRD), Fourier transform infrared microscopy(FTIR), Scanning electron microscope (SEM) analysis.
