| Hydrogen storage on chemical hydrogen storage materials provides the feasibility to meet and exceed the goals of the recent DOE Grand Challenge in Hydrogen Storage for on-board fuel cell applications. We have been investigation the feasibility of using ammonia borane (NH3BH3), and polyammonia borane (-NH2BH2-)n as reversible hydrogen storage materials. This family of molecules is promising given capacity for high volumetric storage densities, ca. >12 weight percent hydrogen, and recent computational results that suggest hydrogen uptake and release is near thermoneutral. The work presented in this symposium will highlight our success in lower the temperature of hydrogen release from ammonia borane (< 100 °C) and to minimize the formation of borazine from polyammonia borane decomposition using mesoporous silica templates (SBA-15). |
