عنوان Synthesis and Characterization of ZrO2 Nanoparticles by an Arc Discharge Method in Water
نوع پژوهش مقاله چاپ شده
کلیدواژه‌ها arc discharge, DI water, photocatalytic activity, ZrO2 nanoparticles
چکیده ZrO2 nanoparticles were produced by high current electrical arc discharge of zirconium electrodes in deionized (DI) water. A mixture of nanocrystalline ZrO2 monoclinic and tetragonal phase form based on X-ray diffraction (XRD) analysis. Dynamic light scattering (DLS) result indicates that the size of the particles increases by increasing the arc current. Absorption spectroscopy of the samples shows a red shift on absorption edge by increasing the arc current. Band gap of the produced ZrO2 nanoparticles at 10 A arc current corresponds to 5.4 eV, which decreases to 5 eV by increasing the arc current up to 20 A.
