Preparation of cobalt nanoparticles by electron beam irradiation

摘要

Cobalt nanoparticles were synthesized by electron beam irradiation without any catalysts at room temperature and ambient pressure.The nanoparticles were characterized by X-ray diffraction,transmission electron microscopy,vibrating sample magnetometer,and laser scattering particle size distribution analysis.Average size of the nanoparticles was about 32 nm with a narrow size distribution.Melting point of the nanoparticles was about 451.3℃.
