Nanowhiskers were found on the surface of carbon gel prepared by using RF gel as a precursor. The results showed that nanowhiskers are formed only on the surface of RF carbon gel prepared under high catalyst concentration. Na 2CO3 was doped to the RF gel of T6, on which the nanowhiskers were not formed after pyrolysis, to confirm the effect of catalyst concentration in RF gel. The result suggested that the catalyst (Na 2CO3) concentration has an effect on the nanowhisker formation.
