Chemical Capping Synthesis of Nickel Oxide Nanoparticles and their   Characterizations Studies
  This work reports aspect related to chemical capping synthesis of nano-sized particles of nickel oxide. It is a simple, novel and cost effective method. The average particle size, specific surface area, crystallinity index are estimated from XRD analysis. The structural, functional groups and optical characters are analyzed with using of SEM, FTIR and UV- visible techniques. XRD studies confirm the presence of high degree of crystallinity nature of nickel oxide nanoparticles. Their particle size is found to be 12 nm and specific surface area (SSA) is 74m2 g-1. The optical band gap energy value 3.83ev has also been determined from UV-vis spectrum.
