AbstractTransition metal phosphide (Fe(2)P, Co(2)P and Ni(12)P(5))-doped carbon xerogels were synthesized by a one-pot pyrolysis of the sol-gel polymer of resorcinol and formaldehyde in the presence of metal nitrates and (NH(4))(2)HPO(4). Various techniques, including: X-ray diffraction, N(2) adsorption-desorption, scanning electron microscopy, transmission electron microscopy and Mossbauer spectra, were employed for characterizing the physico-chemical properties of this kind of phosphide-carbon composites. Comparing with the corresponding metal-doped carbon xerogels, metal phosphides can exert a different influence on the graphitization temperature, textural properties and surface morphology of the resultant carbon xerogels. investigations on the mechanism of iron phosphide formation indicated that CH(4), CO and C acted probably as reducing agents in the carbothermal reduction of metal phosphates. In addition, Mossbauer studies confirmed that this one-pot synthesis method was an excellent way for preparing high purity metal phosphide-doped carbon xerogels. (C) 2008 Elsevier Ltd.
