The effect of the shape of the catalyst on the morphologies of the carbon fibers

Catalytic grown carbon fibers have been synthesized by the decomposition of carbon-containing gases over copper substrate. Metal nitrate was used as the catalyst precursor for the catalyst necessary for the carbon fiber growth. The structural characteristics of the carbon product were assessed from the scanning electron microscopy (SEM). SEM studies have revealed that catalysts have a tremendous impact on the control of the growth characteristics of carbon fibers, and there is a relation between the morphology of the carbon fibers and that of the catalyst.
