Iron‐Fullerene Clusters

Abstract

In this article synthesis, isolation and identification of iron nanoparticles stabilized by fullerenes are described. The synthesis was carried out by a method of iron powder introducing into the stream of carbon-helium plasma at atmospheric pressure. Isolation was implemented by liquid column chromatography with application of Al₂O₃ powder, covered by carbon, as a sorbent. Identification was carried out by method of electron paramagnetic resonance. It has been established, that different fullerenes form clusters with iron particles having different sizes.

Keywords:
