Iron-Containing Carbon Nanocomposites Based on Cellulose

Resumo

Structural transitions of Fe-containing fibrous and microcrystalline flax and hemp cellulose during heat treatment in an inert medium were studied using IR spectroscopy, x-ray diffraction, electron microscopy, thermogravimetric analysis, and N₂ adsorption. Mesoporous ferromagnetic graphitecontaining carbon composites with specific surface area 280-550 m²/g were produced. The nature and shape of the cellulose matrix and the iron-salt anion were found to affect the composition, shape, and size of metal particles and the catalytic graphitization process.
