Nanosized carbon fibers located onto ceramics

Nanosized carbon fibers are of great importance due to its numerous technological applications. One of its disadvantages is low mechanical strength. This problem could be solved by incorporation of carbon fibers into cavities or channels of ceramic monoliths with foam or honeycomb structure. In the present work the experience of preparation of uniform carbon layer consisting from nanosized fibers onto ceramic monoliths with different geometry will be presented. Carbon fibers were produced by catalytic pyrolysis of methane over nanosized metal particles supported over ceramic monolith. Variation of preparation conditions permits to obtain carbon fibers with different density and thickness.
