ABSTRACTPoly(vinylidene fluoride) (PVdF) fine fiber of 200–300 nm in diameter was prepared through the electrospinning process. Dehydrofluorination of PVdF-based fibers for making infusible fiber was carried out using DBU, and the infusible PVdF-based nanofibers were then carbonized at 900–1800°C. The structural properties and morphologies of the resulting carbon nanofibers were investigated using XRD, Raman IR, SEM, TEM, and surface area & pore analysis. The PVdF-based carbon nanofibers had rough surfaces composed of 20-to 30-nm granular carbons, indicating their high surface area in the range of 400–970 m2/g. They showed amorphous structures. In the case of the highly ehydrofluorinated PVdF fiber, the resulting carbon fiber had a smoother surface, with d002 = 0.34–0.36 nm, and a very low surface area of 16–33 m2/g. The hydrogen storage capacities of the above carbon nano-fibers were measured, using the gravimetric method, by magnetic suspension balance (MSB), at room temperature and at 100 bars. The storage data were obtained after the buoyancy correction. The PVdF-based microporous carbon nanofibers showed a hydrogen storage capacity of 0.04–0.4 wt%. The hydrogen storage capacity depended on the dehydrofluorination of the PVdF nanofiber precursor, and on the carbonization temperatures.

The Stability

The hydrogen-rich compound ( H 2)n CH 4 (for n = 1, 2, 3, 4) or for short ( H 2)n M is one of the most promising hydrogen storage materials. The ( H 2)4 M molecule is the best hydrogen-rich compound among the ( H 2)n M structures and it can reach the hydrogen storage capacity of 50.2 wt.%. However, the ( H 2)n M always requires a certain pressure to remain stable. In this work, we first investigated the binding energy of the different structures in ( H 2)n M and energy barrier of H 2 rotation under different pressures at ambient temperature, applying ab initio methods based on van der Waals density functional (vdW-DF). It was found that at 0 GPa, the ( H 2)n M is not stable, while at 5.8 GPa, the stability of ( H 2)n M strongly depends on its structure. We further investigate the Raman spectra of ( H 2)n M structures at 5.8 GPa and found the results were consistent with experiments. Excitingly, we found that boron nitride nanotubes (BNNTs) and graphite and hexagonal boron nitride ( h - BN ) can be used to store ( H 2)4 M , which give insights into hydrogen storage practical applications.
