CARBON NANO-MATERIAL, AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a carbon nano-material, and a preparation method thereof. The carbon nano-material of the present invention comprises a carbon nanofiber containing nitrogen. The method for preparing the carbon nano-material of the present invention comprises the steps of: introducing nitrogen gas into a reactor in the presence of a metal catalyst supported in a support; increasing temperature while supplying a gas mixture of nitrogen gas and hydrogen gas into the reactor; and supplying a nitrogen-containing compound into the reactor. According to the present invention, the carbon nano-material has remarkable durability and can more effectively support a catalyst, and thus performs excellently as a catalyst support. The carbon nano-material of the present invention shows remarkable durability due to excellent crystallinity by introducing nitrogen into a carbon nanofiber, more effectively supports a catalyst, and can improve dispersibility. The carbon nano-material of the present invention is expected to be used as a support of a catalyst including an electrode catalyst of a fuel cell and to be applied to develop a material of various fields.
