Abstract

CTAB and Sonication has been used for preparing Ni(OH)2 nanoparticles by electrolysis at high voltage. The effect of CTAB and sonication on the morphology and size of Ni(OH)2 nanoparticles was observed. The results obtained were characterized with UV-Vis spectroscopy, X-ray Diffraction (XRD), Fourier Transform Infrared Spectrometer (FTIR), and Transmission Electron Microscopy (TEM). The TEM image shows that Ni(OH)2 nanoparticles obtained with and without CTAB under sonication were nearly spherical. UV-Vis Spectrums show that with CTAB has higher concentration in comparison with without CTAB. But no significant different was found for FTIR spectrum. Thermogram shows Ni(OH)2 nanoparticles obtained with and without CTAB have different properties at 60–140 °C due to association of water and CTAB. The most stable Ni(OH)2 nanoparticles were obtained by addition CTAB under …
