Abstract
Results of the synthesis and investigation of gold-carbon nanostructured composites are presented. The parameters of the porous structure of Au/C nanocomposites based on porous carbon materials (PCM) were determined. It was established that the pore size distribution functions calculated according to the nonlocal density functional theory for PCM-1 sample obtained by carbonization of naturally oxidized black coal, and composites based on it, are qualitatively similar, and the positions of major maxima coincide. It was shown that for the decoration of the surface of PCM-2 sample obtained by carbonization of individual aromatic compounds, the major maximum on pore size distribution functions shifts from 9 to 12 E, the maximum with pore size less than 4 E appears. The effect of specific surface of composites on the capacitance of electrodes made of them was studied.
