Xps Oxegen Peak Of Magnetite

Iron oxide particles with the diameter being 5–10 nm were attached onto the sidewalls of multi-walled carbon nanotubes (MWCNTs) by the thermal decomposition of cyclopentadieny iron (II) dicarbonyl dimmer. The red shift of G-mode from 1579 cm − 1 to 1571 cm − 1 in the Raman profile of the decorated MWCNTs is indicative of the attachment of nanoparticles.

Effect of the background subtraction method In the analyzed sample (magnetite), iron was present in two states: Fe2+ and Fe3+. The back- ground subtraction was done in the same way as for the reference spectrum. The B parameter val- ues obtained were B = 3220 eV2 for ‘‘Tougaard’’ and B = 1420 eV2 for ‘‘Seah’’.

Electron energy loss spectroscopy and X-ray photoelectron spectroscopy analyses reveals that the attached nanoparticles are composed of a maghemite phase. Transmission electron microscopy suggests the maghemite particles are covered with amorphous carbon materials and form a core–shell structure.
