In fig.1 dependences of catalytic activity of metal containing samples СM KAU from reaction
temperature are resulted. It is visible, that cobalt containing АС develops the best results in
conversion СO. Activity of contacts decreases in a correlation line Со > Ni > Fe.
We have compared catalytic activity of two carbon matrixes SCN and KAU, which had the
various nature /an origin (table 1) and have determined the contribution of a cellular structure
of nitrogen containing CM on conversion CO.
In the table temperatures of achievement of complete conversion CO on metal-carbon
catalysts are presented

СА SCN have appeared more active and have effectively reduced temperature of full
conversion CO (for Co - 5С, for Ni - 15С and for Fe - 113С). This СА differs not only a
cellular structure, but also presence of nitrogen Thus influence of the chemical nature of a
surface of CM consists in influence of structure and influence of available heteroatoms
(Co and N are most essential).
In this work the modification of a surface of mesoporous AC KAU and SCN by
compounds of Со, Ni, Fe was realized. The study of catalytic properties Co/Ni/Fe compounds
supported on carbon matrix in СО oxidation was investigated.
