Synthesis and properties of magnetic composites of carbon nanotubes/Fe nanoparticle

Language

Abstract

Magnetic composites of carbon nanotubes (CNTs) are synthesized by the in situ catalytic decomposition of benzene at temperatures as low as 400°C over Fe nanoparticles (mean grain size 26 nm) produced by sol-gel fabrication and hydrogen reduction. The yield of CNT composite is up to about 3025% in a run of 6 h. FESEM and HRTEM investigations reveal that one-dimensional carbon species are produced in a large quantity. A relatively high value of magnetization is observed for the composite due to the encapsulation of ferromagnetic Fe 3C and/or α-Fe. The method is suitable for the mass-production of CNT composites that contain magnetic nanoparticles. © 2009 Chinese Physical Society and IOP Publishing Ltd.
