Texture and microstructure of NiO derived from Ni(OH)2 in vacuum
The textural and structural characteristics of NiO obtained by the thermal decomposition of Ni(OH)2 in vacuum up to 500 °C are studied by the analysis of nitrogen adsorption measurements and X-ray line profile analysis. The decomposition occurs via the formation of a network of cracks and a slit-shaped porous system that changes to cylindrical on increasing the temperature. The particles are composed of small crystallites with most of their surface exposed to gas adsorption. A significant microstrain content is observed in all samples.
