Abstract :

Nanostructured oxides are gaining continuous importance for various applications due to their unique physical and chemical properties based on the size-homogeneity and large specific surface area. Crystallography and size of the nanomaterials greatly affect their applications in designing optical, electronic, magnetic and catalytic materials. NiO is an important inorganic oxide extensively used in catalysis, battery cathodes, electrochromic films, and magnetic materials. Nanocrystalline NiO is believed to have many better properties than those of micrometer-sized NiO particles in terms of the volume effect, the quantum size effect, the surface effect. The present work represents an attempt to synthesize of suitable NiO-nanoparticle for the design of high performance novel nanocomposite materials. The effect of synthesis conditions on morphology development and surface area was experimentally investigated. Nano-NiO particles have been obtained by thermal decomposition method using NiCl2 and NH3.H2O as the raw materials. After calcination process of the Ni(OH)2 precursors at 400-500�°C for 1 h, green Ni(OH)2 precursors have been transformed into black NiO nanoparticles. XRD patterns of NiO nanoparticles confirmed the conversion of Ni(OH)2 into NiO nanostructure. Nanostructures were also confirmed SEM, TEM, FTIR, Raman and Uv-vis analyses. Analysis results reveal that the synthesized nanoparticles have cubic particles with an average diameter of around 8-13 nm. The NiO nanoparticle obtained at 400�°C with the highest surface area and small crystal size has been chosen as a suitable dopant to design new nanocomposite materials.
