| Abstract: | Nickel nanoparticles have been synthesized using nickel nitrate, vegetable
oil and sucrose. Ethanol has been used as a solvent since the heat of reaction
shows the destabilization of nickel particles if water is present in the
synthesis mixture. Nickel with fcc phase is obtained by reduction with sucrose
followed by stabilization using vegetable oil. Nickel or possibly nickel
carbide with hcp structure is obtained by treatment with a mixture of
oleylamine and methanol. The fcc and hcp crystal structures have been
characterized by XRD. The calcination of nickel nanoparticles at 450 °C results
in the sintering of nickel nanoparticles, thereby increasing the crystallite
size. The scanning electron micrograph reveals that the particle size is in the
range of 5 – 58 nm for fcc-Ni nanoparticles calcined at 450 °C for 10 min. |
