The study of thermal oxidation in air of carbon matrix in the presence of nanosized particles of filler - cobalt oxide Co3O4, as well as mixed oxides NiCo2O4 and ZnxCo1-xOy was carried out. The particles of transition metal oxides were created by thermal decomposition of precursor compounds (azides and hydroxides). It is shown that vigorous oxidation in the air of the porous carbon matrix starts after the formation of Co3O4 at temperatures above 300 ° C. The intensity of oxidation is directly proportional to the filler concentration in the carbon-transition metal oxide composite system. Carbon matrices based on multilayer carbon tubes show higher resistance to oxidation processes.
