英文摘要	Carbon encapsulated Cu nanoparticles were successfully prepared by DC arc discharging plasma technology. The product was characterized by X-ray diffractometry (XRD), high resolution transmission electron microscopy (HRTEM) and low-temperature N2 adsorption desorption to determine the morphology, crystal structure, particle size, specific area and pore structure. The results indicate that the carbon encapsulated copper nanoparticles have typical core shell structure, the core is metal face centered cubic structure copper, and the outer shell is graphite carbon layer. The particles morphology mainly exhibit spherical or ellipsoidal shapes with relatively uniform particle size and good dispersion. The particle size distribution is in the range of 20-100 nm, the average particle size is 50 nm, and the thickness of the shell carbon layer is about 10 nm. The N2 adsorption and desorption isotherm belongs to type IV, most of pores between grains are mesoporous pore, the BET specific surface area is 33 m2/g, and the equivalent particle size is 45 nm, which is consistent with the results measured by TEM and XRD. The BJH adsorption cumulative pore volume and adsorption average pore size are 0.112 cm3/g and 13 nm, respectively. © 2017, Science Press. All right reserved.
