The results indicated that the purity and yield of the secondary product were higher notability than the first product, which improved the lower purity and yield of coal derived carbon nanotubes in the classic method.

In order to select suitable catalyst from four metals(Fe、Co、Ni、Mo)to synthesize carbon nanofibers/carbon nanotubes on carbon fibers,by the impregnation-reduction method and chemical vapor deposition method were used four metal—salts separately as catalyst precursor,CO as carbon source,H_2 as reduction gas,N_2 as carrier gas.

In order to in situ growing carbon nanofibers/carbon nanotubes on carbon fibers for further investigating the application of carbon nanofibers/carbon nanotubes in C/C composites,nano-nickel catalyst particles were coated on the carbon fibers' surfaces by KOH-impregnation-reduction method.

In order to grow carbon nanofibers/carbon nanotubes on carbon fibers,and further investigate their effect on the interface microstructure and thermal conductivity of C/C composites,nano Ni catalyst particles were coated on the surfaces of carbon fibers by impregnation-reduction method using Ni(NO3)2 as catalyst precursor,H2 as reduction gas and N2 as carrier gas.
