Nickel-based carbon fiber has been utilized for the steam reforming of methane. In the fuel cell system, cheap nickel-based carbon fiber was considered as alternatives to platinum catalysts. By using lignin and PAN complex, renewable carbon fiber was fabricated to support the formation of cystalline nickel nanoparticles on the fiber surface. This composite fiber can be easily prepared by electrospinning, thermal stabilization, and carbonization. Especially, porous carbon fiber could be prepared using PVDF and PLA. We analyzed the relationship between the porous structure of carbon fiber and the crystal structure of nickel species. Each sample was characterized by scanning and transmission electron microscope (SEM and TEM) and X-ray diffraction (XRD) patterns. This study was supported by the Human Resource Development Programs for Green Convergence Technology funded by the Korea Ministry of Environment (MOE)
