For the first time, we report the novel synthesis of
flocculus-like spheres of nickel hydroxy hydrate with grain size of similar to 7nm via the
thermolysis of nickel phthalate polymer. Nickel phthalate polymer formulated as [Ni(Pht)(H(2)O)]
(n) was simply prepared via a precipitation procedure by mixing of 1,2-benzenedicarboxylic acid
(phthalic acid) to nickel acetate salt under basic condition. Nickel hydroxy hydrate
nanostructures were obtained by thermolysis of [Ni(Pht)(H(2)O)](n) polymer in the presence of
oleic acid (OA) at 190 degrees C and NiO nanoparticles were formed via the thermolysis of nickel
phthalate polymer in the presence of oleic acid and triphenylphosphine (TPP) at higher
temperature. Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), X-ray
diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM)
were applied for the characterization of products. The magnetic property of NiO nanoparticles
were studied with vibrating sample magnetometer (VSM) at 300 K.
