Description
Summary:With a gravimetric hydrogen density of 19.6 wt % and the capability of storing up to 146 kgH2  m–3, ammonia borane (NH3·BH3) possesses excellent hydrogen storage properties. Nanoconfinement in six different porous metal–organic frameworks with MIL-53 topology is shown to reduce the hydrogen release temperature and modify its decomposition pathway. In particular, the modification of terephthalic acid as linker by OH and NH2 groups resulted in reduced hydrogen release temperatures and reduced formation of gaseous byproducts. In situ XRD diffraction and 11B MAS NMR studies helped to confirm the stability of the porous host and identify ammonia borane decomposition products.
