Carbon whiskers were produced in the gas phase by thermal decomposition of benzene in the presence of a catalyst. The effects of operation conditions such as the concentration of sulfur compound and feed temperature on product yield and the form of whiskers were investigated. Morphology and crystallinity of carbon whiskers and analysis of catalytic particles were characterized by SEM, TEM and X-ray diffraction. Sulfur was effective over a range of S/Fe (atomic ratio of sulfur to iron) from 0.17 to 0.52 on the formation of carbon whiskers. Thiophene was more effective than hydrogen sulfide on the yield of whiskers. The growth of whiskers was promoted over 720°C.
