Abstract: X-ray diffraction studies of nanoporous carbon synthesized from silicon carbide have been performed. The coordination shell radii and the coordination number in nanoporous carbon have been calculated using the Finback method. It has been shown that, when the coordination shell radii coincide, the distribution of carbon atoms over the coordination shells differs from that of hexagonal graphite. Based on an analysis of the interference functions and the results of the calculation, a model of atomic arrangement in the region of short-range ordering has been constructed. It has been demonstrated that the model cluster consists of seven graphene networks with different curvature radii.
