The DOE has recently issued a Grand Challenge in Hydrogen Storage. The ambitious goals for volumetric and gravimetric densities and the controlled release of H 2 from materials at temperatures below 80°C contained within this Grand Challenge demand the discovery of new materials and catalysts. The chemical and physical properties of amine borane complexes was studied. Transition metal species during the progression of the reaction were observed. The predominant species observed during H 2 evolution did not appear to be colloidal but most likely was composed of 2-6 Rh atoms surrounded by tightly bound external ligands. This result was in contrast to previous conclusions that suggest the mechanism involves a heterogeneous catalyst.
