NiO nanoparticles were successfully prepared by solid state thermal decomposition of NiCO3 (10 nm) precursor,which was synthesized by solid state reaction at room temperature.The crystal structure,particle-size and properties of the nanoparticles were characterized by means of XRD,TEM TG-DTA and BET.The results show that the NiO had an average particle size of 5.8 nm and highest BET specific surface area of 116.6 m2/g after annealling the precursor at 300℃ for 2 h.The formation mechanism of the nanoparticles were also discussed.
