摘要

PVC-based carbon nanofibers with graphitic nanoparticles were fabricated by an electrospinning-carbonization technique and characterized by SEM, (HR)TEM and XRD. The hydrogen storage capability of the resultant nanofibers was evaluated using the volumetric method. The results show that the PVC-based carbon nanofibers obtained from the electrospun PVC/NiCl_2 nanofibers consist of both amorphous carbon and a well-grown graphite layered sphere with a diameter of 35 nm. It is clear that the iodine treatment is essential for retaining a fibrous shape during the carbonization, and Ni is beneficial to the growth of graphitization at low temperatures. The hydrogen storage capacity of the PVC-based carbon nanofibers obtained at 1000℃ is 0.30 wt%, suggesting that the resultant nanofibers are a potential energy storage material.
