Synthesis of platelet carbon nanofibers by an injection CVD method and their applications in hydrogen storage

An effective production of platelet carbon nanofibers (PCNFs) was obtained in the presence of sulfur in the catalytic solution by an injection chemical vapor deposition (CVD) method using alcohol as the carbon source, ferrocene as the catalyst, and thiophene as the promoter. Due to the simplicity of the present technique, the injection CVD method may be suitable for scale-up for mass production. Furthermore, the hydrogen storage capacity of the material was measured by volumetric method and the study was carried out at 77 K and the pressure up to 1 MPa. The result showed that the PCNFs can have a hydrogen storage capacity of more than 0.5 wt%. We believe that the material is potential for energy storage (hydrogen, methane).
