عنوان انگلیسی Green Synthesis of Zinc Oxide Nanoparticles using Garlic skin extract and Its Characterization
چکیده انگلیسی مقاله Plant-mediated synthesis of metal oxide nanoparticles is a promising alternative to the traditional method of physical and chemical synthesis. In this paper, we report the green synthesis of zinc oxide nanoparticles (ZnONPs) by a biological method. During the study, Zinc oxide nanoparticles were synthesized by Allium sativum skin (garlic skin) extract. Formation of zinc oxide nanoparticles has been confirmed by UV-visible spectroscopy, UV diffuse reflectance spectroscopy (UV-DRS), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscope with Energy dispersive X-ray studies (EDX) and transmission electron microscope (TEM), Atomic force Microscopy (AFM), Brunauer-Emmet-Teller (BET), Thermogravimetric analysis (TGA). UV-vis spectroscopy confirms the synthesis of zinc oxide nanoparticles and showed the characteristic of absorption peak at 370nm. The scanning electron microscope and Transmission electron microscope confirms the formation of the rod and hexagonal shaped nanoparticles having average size 7.77 nm. Energy dispersive X-ray analysis states the formation of highly pure zinc oxide nanoparticles. The zinc oxide nanoparticles synthesized using garlic skin are expected to have applications in biotechnology, biomedical, catalysis, coatings, sensors and water remediation. This green approach for the synthesis is a cheap, novel, eco friendly and convenient method.
