dc.description.abstractIntermetallic (Co-Sn, Ni-Sn, Co-Ni) nanoparticles are synthesized through a borohydride reduction in a mixture of aqueous solutions of CoCl2.6H2O, NiCl2.6H2O and SnCl2.2H2O salts at room temperature applying a template technique. A carbon support is used. As a result nanocomposite materials are obtained in situ. The ratio of the metallic components is chosen on the ground of the phase diagrams of the relevant binary (Co-Sn, Ni-Sn, Co-Ni) systems: Co:Sn = 35:65, Ni:Sn = 45:55, Co:Ni = 50:50. Graphite and carbon powders are used as a carbon support. To avoid the nanoparticle's aggregation β-cyclodextrin is added to the reaction solutions. EDS and XPS investigation methods are applied to study the surface composition of the synthesized intermetallic nanoparticles and their carbon nanocomposites. A particle's morphology is typical for the alloyed materials. The nanoparticles are characterized by a relatively high specific surface area. Both the elemental and phase composition of the investigated particles and their carbon composites do not alter with the change of the carbon support. They depend only on the ratio between the respective metal components set in the starting reaction solutions according to the phase diagrams of the corresponding binary systems. The studies conducted on the intermetallic nanoparticles synthesized with various carriers demonstrate that they are suitable to be used as catalysts, electrode materials in Li-ion batteries and as magnetic materials for biomedical applications.
