Intermetallic (Co-Sn, Ni-Sn) nanoparticles are synthesized through a borohydride reduction with NaBH4 in a mixture of aqueous solutions of CoCl2.6H2O, NiCl2.6H2O and SnCl2.2H2O at different mass ratios Co:Sn and Ni:Sn. Subsequently, carbon - based nanocomposites are obtained. A "template" technique which involves borohydride reduction of intermetallic nanoparticles on a support (carbon foam, carbon powder , graphite ) is used. Samples are studied by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) analysis. The influence of the different supports used on the morphology, structure, phase composition and element composition of the synthesized composite materials is investigated. Phases, CoSn2 (Co: Sn = 1:2), Co3Sn2 (Co: Sn = 3:2), Ni3Sn2 (Ni: Sn = 3:2), Ni3Sn (Ni: Sn = 3:1) are achieved. They are in correspondence with the phase diagrams of the Co-Sn and Ni-Sn binary systems.
