Synthesis of nanosized α-nickel hydroxide by a sonochemical method

Nanosized alpha-nickel hydroxide with an interlayer spacing of 7.2 Angstrom has been synthesized with the aid of ultrasound radiation. This method was found to be a simple and convenient method to produce alpha-nickel hydroxide, The synthesized hydroxide was found to possess good stability in KOH medium and the material might be interesting from the application point of view in secondary alkaline batteries. The alpha-nickel hydroxide has been characterized by powder X-ray diffraction, transmission electron microscopy, DSC, thermogravimetric analysis, FT-IR spectroscopy, and elemental analysis.
