Abstract

Nickel hydroxide nanoparticles with different amounts of cobalt atoms in the structure forming a unique material, were synthesized by using ultrasonic radiation. The particles of 5 nm diameter were prepared and characterized by X-Ray diffraction, Raman and Infrared spectroscopies, and thermogravimetry. The incorporation of cobalt leads to distinct crystalline planes, showing an opened and disarranged structure, indicating the stabilization of the alpha-Ni(OH)2 phase.
