Raman spectra of iron-containing glassy carbons

Abstract Iron-containing glassy carbons were prepared from carbonization of the copolymers of furfuryl alcohol with one of the ferrocene derivatives. Their structural changes with heat treatment were studied with X-ray diffraction and laser Raman spectroscopy. Addition of iron to glassy carbons decreases both the half band width and intensity of a defect-induced Raman band at 1360 cm −1 at temperatures as low as 700°C and accelerates carbonization and graphitization of carbon precursors.
