| Abstract: | Carbon encapsulated Fe nanoparticles were prepared by carbonizing the mixture of cellulose and nitric iron in flowing hydrogen.Characterization by TEM,EDX and XRD demonstrates that carbon encapsulated Fe nanoparticles thus prepared have a core-shell structure and narrow size distribution.The electromagnetic property of the carbon encapsulated Fe nanoparticles was also analyzed by wave-guide method in the frequency range of 8.2-12.4 GHz with vector network analyzer. |
