FIELD: carbon materials.
SUBSTANCE: invention is directed to manufacture fillers of composites or catalyst supports, sorbents, and hydrogen accumulators. Iron-containing catalyst is charged into reactor and calcined under inert gas (e.g. nitrogen or argon) at 850-1200°C for 2-3 h, after which catalyst is cooled to 400-500°C and carbon monoxide is fed into reactor to be decomposed at this temperature on iron-containing catalyst.
EFFECT: increased yield of nanofibers, narrowed their diameter variation range, and lowered synthesis temperature.
