Abstract
Sulfur encapsulated in single-walled carbon nanotubes (S@SWCNTs) represents a composite material hitherto unexplored for hydrogen storage. Interactions between sulfur and carbon nanotubes modify the electronic properties of the composite, thus offering methods for improving hydrogen sorption in carbon nanotubes. Here we demonstrate that S@SWCNT composites can provide 35 % greater excess adsorbed hydrogen per specific surface area, and improved hydrogen uptake at lower pressures (
