Preparation of Nickel Nanoparticles by the Thermal Decomposition of NiC₂O₄. 2H₂O Precursor in the Argon Gas

Abstract:

Nickel nanoparticles are successfully obtained by the pyrolytic decomposition of NiC₂O₄. 2H₂O in the argon gas. The pyrolysates of NiC₂O₄. 2H₂O in the argon gas are investigated by TG-DSC and TEM. The results show that there are two stages in the process of the pyrolytic decomposition of NiC₂O₄. 2H₂O in the argon gas. The crystal water in NiC₂O₄. 2H₂O is lost from 200 °C to 300 °C. NiC₂O₄ is pyrolysized into nickel powder from 325 °C to 425 °C. At the same time, the influence of temperature on the particle size of the decomposition is more from 254.4 °C to 407.5 °C. The influence of temperature on the particle size of the decomposition is less from 407.5 °C to 450.0 °C. Therefore, the pyrolytic condition of NiC2O₄. 2H₂O in the air is controlled if nickel nanoparticles are prepared.
