Abstract:
Nickel doped Zinc Oxide nanoparticles were synthesized by Micro-wave assisted technique from the chlorides of Zinc (II) and Nickel (II). Initially 0.2 mol of Aqueous ZnCl2 was taken, added with acetic acid and continuously Stirred at 300 RPM. Later NaOH solution is added to the above prepared solution till it reaches PH 7. Given Molar Percentage of Nickel Chloride (Pure, 0.01, 0.02, 0.03, 0.04 mol) added for Doping at PH = 7 of the solution and stirred for 10 minutes. The prepared solution is placed on magnetic stirrer and then heated under Microwave for 20 minutes with 5 minute interval, observed the gel like form and finally prepared powder was filtered. The filtered and dried powder was then calcinated at 5000 C for 1 hour. The synthesized nanoparticles were characterized for determining the atomic and molecular structure of material by X-ray diffraction, size and morphology by Scanning Electron Microscopy, elemental composition by EDAX, Band Gap by UV-VIS spectroscopy, Mode of Vibration by Raman Spectroscopy. SEM analysis results revealed the formation of Hexagonal nuts like structure of ZnO with porous or rough surfaced Nanoparticles. The doping of Nickel was revealed by the formation of new peaks when compared to that of un-doped ZnO, with average crystallite size of 45nm while smallest size is 8nm. Scanning Electron Microscopy images showed random shape, hexagon nut, morphed plates has hole at center (Nut) and small rods with particles morphology for un doped ZnO to doped ZnO. The change in morphology was observed with addition of Nickel dopant acts as a catalyst for morphology change and self-assembling. UV-VIS spectroscopy shows the increase in band gap due to the replacement takes place of Nickel ions in Zinc matrix. This shows an increase in electrical conductivity activity and higher thermal conductivity in transformer cooling oil application.
