ABSTRACT
Aligned CN[SUBx] nanotubes filled with Fe[SUB2]O[SUB3] particles were synthesized through a single pyrolysis reaction of acetonitrile and Fe[SUB2]O[SUB3]/SiO[SUB2] catalyst at 900°C under Ar[SUB2] flow. The number and spacing of the encapsulated (Fe[SUB2]O[SUB3] particles inside the CN[SUBx] nanotubes were controlled by adjusting the amount and time of acetonitrile feeding. The chemical composition and atomic structure of the nanocapsulates were investigated using combined techniques of high-resolution electron microscopy, electron energy loss spectroscopy (EELS), and elemental mapping. It was found that the encapsulated particles were (Fe[SUB2]O[SUB3] particles and that the doped nitrogen atoms, which were mainly pyridine-like, bonded with two carbon atoms within the graphene sheets, giving rise to a π*-type peak at around 399 eV in EELS spectra.
