Out of many hydrogen storage systems, chemical hydrides not only have a high hydrogen storage capacity, but also produce ultrapure hydrogen in presence of adequate catalysts at room temperature. Among many chemical hydrides, ammonia borane (NH3BH3) is one of the promising candidates because its intrinsic hydrogen content is as high as 19.6 wt%. Moreover, the spent products of ammonia borane are non-flammable and rarely toxic. The chemical hydride fuel system was prepared by pulverizing ammonia borane and Ni-Co/r-GO catalysts in a high-energy ball mill. The hydrogen was produced from catalyzed hydrolysis reaction of ammonia borane composite initiated with limited amount of water. Variable parameters such as the amount of water dosage and loading of catalysts will be discussed in this study. ? 2014 The Authors. |
