Abstract
Modified carbon sorbents containing silicon oxycarbide, which did not form a continuous protective layer on the surface, were prepared by the liquid-phase supporting of polycarbosilane onto the surface of carbon sorbents followed by thermal treatment. The silicon-containing sorbents were characterized by increased stability to oxidation by atmospheric oxygen at high temperatures (as compared with that of the initial sorbents) with the retention of sufficiently high sorption activity.
