Nanostructured Ni Powder Synthesized from Non-aqueous Bath

Abstract

Dendritic nickel agglomerates composed of nickel nanoparticles have been synthesized through one-step electro-deposition using NiCl₂·6H₂O as precursor and ethanol as solvent. Analytical results by X-ray diffraction (XRD) and selected area electron diffraction (SEAD) indicate that the as-prepared products belong to face-centered cubic structure of nickel nanoparticles with high purity. Morphological observation reveals that the deposits are mainly dendritic containing nanoparticles. The magnetic properties of deposits have also been measured at room temperature and the results show that the saturation magnetization increases and the coercivity decreases as increasing the NiCl₂·6H₂O concentration.
