NiO Nanoparticles: Synthesis and Characterization

In  the  current  paper,nanostructured  nickel  oxide  (nio)  were synthesized  by  co-precipitation  method  using  nickel(ii)  chloride hexahydrate  (nicl2.6h2o)  and  sodium  hydroxide    (naoh)  as starting  material.  structural,  optical  and  magnetic  properties  of nanostructures  were  characterized  by  x-ray  diffraction  (xrd), scanning  electron  microscopy  (sem),  atomic  force  microscope (afm), uv–vis absorption; fourier transformed infrared (ftir) and vibrating  sample  magnetometer  (vsm)  technique.  the  x-ray diffraction  pattern  studies  revealed  the nio  have  a      face-centered cubic (fcc) structure and confirmed  the presence of high degree of crystallinity nature nio nanoparticles that their average size is found to  be  26  nm.  the  composition  of  nanostructures  confirmed  by analysis of ftir  spectra. the  average  size  of  the nio nanoparticle observed  from  scanning  electron microscopy  images  is  found  to be dimensions  about  24  nm.  magnetic  measurement  confirmed  the nickel  oxide  nanostructures  superparamagnetic  behavior  at  room temperature (rt) after calcinations.
