Abstract

AbstractAn efficient and simple wet chemistry methodology to synthesize iron filled singlewalled carbon nanotubes (Fe‐SWCNT) is presented. The route leads to the formation of long continuous iron cables within the tubes. Partial filling is also observed. The morphology, high filling aspect and the chemical profile of the produced sample is studied by high resolution transmission electron microscopy and its X‐ray energy dispersive spectroscopy (EDX) mode. The bulk scale chemical composition is confirmed with a bulk sensitive electron energy‐loss spectrometer (EELS). The resulting material exhibits ferromagnetic properties at room temperature and 3 K.
