Abstract
Metal-carbon nanocomposites, the structure of which is a carbon matrix with nanoparticles of a Fe–Co solid solution uniformly distributed in it, are synthesized by pyrolysis of a precursor based on chitosan and iron and cobalt nitrates under the action of infrared radiation in the temperature range 500–700°С. The features of the formation of nanoparticles of an Fe–Co solid solution are studied by X-ray diffraction depending on the synthesis conditions and the ratio of the metals in the system. The experimentally determined values of the lattice parameters are used to estimate the composition of the forming bimetallic Fe–Co nanoparticles. The morphology and dispersion of metal nanoparticles are studied by transmission electron microscopy. Elemental analysis of the samples under study is carried out by the methods of X-ray fluorescence analysis and X-ray photoelectron spectroscopy.
