The present invention relates to a
hydrogen storage composition prepared in accordance with a method comprising: (a) combining (i) a metalliferous material selected from the group consisting of: (A)
metal or a
metalloid, or an
alloy thereof, or a compound thereof, or an homogeneous or an inhomogeneous combination of at least two of a
metal or a
metalloid, or an
alloy thereof, or a compound thereof, or (B) a
hydride of any of: a
metal or a
metalloid, or
alloy thereof, or a compound thereof, or an homogeneous or an inhomogeneous combination of a metal or a metalloid, or an alloy thereof, or a compound thereof, with ii) a liquid consisting essentially of any of: water, at least one
alcohol, or a mixture of water and at least one
alcohol, to form a first intermediate; and (b) milling the first intermediate for form an
hydrogen transfer facilitator; (c) combining the
hydrogen transfer facilitator with a second metalliferous material selected from the group consisting of: (A) a metal or a metalloid, or an alloy thereof, or a compound thereof, or an homogeneous or inhomogeneous combination of at least two of a metal or a metalloid, or an alloy thereof, or a compound thereof, or (B) a
hydride of any of: a metal or a metalloid, or an alloy thereof, or a compound thereof, or an homogeneous or inhomogeneous combination of at least two of a metal or a metalloid, or an alloy thereof, or a compound thereof, such combining effecting sufficient contact between the
hydrogen transfer facilitator and the second metalliferous material so that the
hydrogen transfer facilitator is configured to effect absorption or
desorption of hydrogen by the second metalliferous material.
