Bimetallic Fe-Co catalysts supported on nanometric SiC powder were prepared by wet impregnation method and were used to catalyze CNTs from decomposition of acetylene at 850ͦC by TCVD. The effect of Fe and Co combination ratio in catalytic basis on properties of end product CNTs was investigated using XRD, SEM, TEM and Raman spectroscopy. The results revealed that iron and cobalt are in oxide and cobalt ferrite forms.The best growth of CNTs on catalyst sample with wt% Fe:Co:SiC=10:10:80 was achieved. It was observed that the ratio of Fe:Co loading in catalyst-substrate composition is an important factor which can affect the activity of catalytic basis and the characteristics of grown CNTs such as the density and average diameter.
