Low Temperature Condition For Nio Nanoparticles Preparation Via Sol‐Gel Method

Abstract
Nickel oxide (NiO) nanoparticles had been widely used in semiconductor, magnetic and fields due to its high surface area, adsorptive and diffusivities properties. In this study, NiO was prepared via sol‐gel method under low temperature operating condition. The properties of NiO nanoparticles were investigated by XRD, FTIR, TEM and TGA analysis. TGA had confirmed the organic compound decomposed at 400oC and NiO nanoparticles were formed at this temperature. The structure of NiO nanoparticles obtained was cubic structure. The spherical shape of NiO nanoparticles was observed by TEM with average particle size of 18.11 nm which was close to the average particle size calculated using XRD analysis of 22.78 nm. The sol‐gel method showed an easier way to produce smaller size of NiO nanoparticles at low temperature. Index Terms— Nickel Oxide, Nanoparticles, sol‐gel method, low temperature
