Nanoscale Materials for Hydrogen-Storage
The major bottleneck for commercializing fuel cell vehicles is onboard
hydrogen storage. Hydrogen may be stored in solids by two principle
mechanisms: i) Adsorption of hydrogen molecules on surfaces, i.e.,
physisorption. ii) Hydrogen atoms dissolved or forming chemical bonds,
i.e., chemisorption. Our present studies focus on novel nanoscale
materials with high specific surface area and microporosity. Carbon
nanostructures, as activated carbon or single-wall nanotubes, store only
small amounts of hydrogen at room temperature, however, at low
temperature the adsorption due to physisorption is appreciably higher
and depends linearly on the specific surface area.
These studies are
extended to metal-organic frameworks (MOFs) which are the lightest known
crystalline solids possessing an extremely large specific surface area
and high microporosity.
