| Abstract: | Carbon encapsulated Ni core-shell structure nanoparticles were successfully prepared by anodic arc discharging plasma method and subsequently purified with acid treatment and magnetic separation.The composition,morphology,microstructure and particle size of the products by this process were investigated via the high-resolution transmission electron microscopy(HRTEM),X-ray diffraction(XRD),transmission electron microscopy(TEM) and X-ray energy dispersive spectrometry(XEDS).The results show that the carbon en... |
