The Influence of the Hydrothermal Temperature on the Morphologies of β-Ni(OH)₂ Nanospheres and Nanoflakes

Abstract:

β-Ni(OH)2 nanospheres and nanoflakes have been successfully synthesized with nickel nitrate as nickel source and stronger ammonia water as precipitant via the hydrothermal method. The phase and the morphologies of the samples have been characterized and analyzed by XRD (X-ray diffraction) and SEM (Scanning electron microscope), respectively. XRD analysis shows that the phase of the samples is β-Ni(OH)2. SEM analysis confirms that the low reaction temperature is propitious to the synthesis of β-Ni(OH)2 nanospheres. However, The high temperature is in favor of the synthesis of β-Ni(OH)2 nanosflakes.
