Ammonia borane has been adsorbed into mesoporous carbon cryogels in an effort to manipulate the hydrogen release properties. TEM studies showed that ammonia borane was incorporated into the cyrogel structure. Thermochemical analysis of the dehydrogenation indicated that the hydrogen release properties of ammonia borane were enhanced when incorporated into cryogels. Dehydrogenation occured at lower temperatures and the non-hydrogen volatile products were controlled, liimiting borazine formation.
