Energy Storage

X-ray Photoelectron Spectroscopy (XPS) and X-ray Adsorption Spectroscopy (XAS) show that in situ atomic hydrogen treatment of single-walled carbon nanotubes (SWCN) film causes the formation of the C-H bonds between hydrogen atoms and carbon atoms at the SWCN surface. The study indicates that carbon nanotubes with a diameter of around 2.1 nm can have a hydrogen storage capacity of more than 7 wt % through the formation of the stable C-H bonds.
