Synthesis and characterization of zinc oxide nanoparticles by modified sol-gel method

Abstract

In die present work a modified sol-gel method is used for the synthesis of ZnO nano particles using zinc acetate dibydrate, ethylene diaminedihydrochloride and NaOH as precursors and poly(vinyl pyrrolidone) as surfactant to control the morphology and shape of synthesized ZnO nanoparticies. Poly(vinyl pyrrolidone) are used as capping agent and distilled water as solvent, using magnetic stirrer. The synthesized ZnO nano particles are dried in oven at 100 °C for 2 h and then calcinated at 500 °C in muffle furnace for 2 h. The synthesized nanoparticles were characterized by using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectra and Fourier transform infrared spectroscopy.
