The structure and surface morphology of graphite nanoplatelets (GNPs) modified by bimetallic Ni-Fe phase with 80% mass. Ni and 20% mass. Fe is investigated by the methods of scanning electron microscopy and X-ray analysis. The bimetallic active phase is applied onto GNPs surface with impregnation method using nitrate solutions of metals. The prepared Ni80Fe20/GNPs composite demonstrated high catalytic performance in the reaction of CO2 methanation. At the temperature range of 350-450°C, it exhibited a high efficiency of CO2 conversion compared to bulk Ni80Fe20. The thermoprogrammed desorption study of the surface condition of the Ni80Fe20/GNPs composite after exposition in the catalytic process showed that H2O (m/z = = 18), CO (m/z = 28) and CO2 (m/z = 44) particles are desorbed from the surface.
