Chapter 37 Influence of CTAB and Sonication on Nickel Hydroxide Nanoparticles Synthesis by Electrolysis at High Voltage

摘要

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 sonication.
