The present invention relates to physical chemistry.
The material is made as a three-dimensional matrix with a pore volume of from 0.2 to 1.7 cm3 /g. The matrix is formed by bent layers of carbon of 100-10,000 Å thickness and 100-10000 Å radius of curvature. The true density of the material according to the present invention is 1.80-2.10 g/cm3, its X-ray density is 2.112-2.236 g/cm3, the pore size distribution has its maximum within the range of 200-2,000 Å.
The present invention can be useful in, for example, in the production of catalysts.
