The pore structure of origin grains of dispersive carbon plays the role of reinforced
framework, which determines the space arrangement and the size of microcrystals in forming
pyrolitic carbon layers. After that the reinforced framework can be moved off at carbon
material activation. As the result the pyrolitic carbon matrix is formed, physics and chemical
properties of which are determined by the synthesis conditions [2].
The multistage technology allowed to modify the carbon material by heteroatoms on the
stage of carbon-carbon composite formation. This material keeps all the properties which are
intrinsic for pyrolitic carbon: mechanical strength, thermo and chemical stability under
mesopore part up to 80% of total pore volume and pore sizes 2-10 nm. This material acquired
new surface properties, which influenced on the supported catalysts state [3, 4].
In this work the methods of modifying of carbon-carbon composites by heteroatoms are
considered and the peculiarities of their microstructure, texture and chemical composition are
adduced. The conditions of supporting of active components: Cu, Ru, CeO 2 , Ru-Cs on
modified sibunits is investigated.
The activity of catalysts on the basis of heterocarbons supports in the reactions of CO
oxidation and ammonia decomposition under low temperatures are given.
It is shown that the obtained catalysts activity is on the same level or even on the higher
one than the activities of the best catalysts for these reactions.
