Among various chemicals used as hydrogen storage media, chemical hydrides such as ammonia borane (AB) have attracted the most attention recently, especially after the US DOE determined that sodium borohydride (NaBH4) could reach previously set 2010 goal on hydrogen storage capacity at 6 wt% but fails to achieve that in 2015 at 9 wt%. In this study, we aim to establish the way to characterize the product before and after the reaction of ammonia borane by hydrolysis in presence of as-synthesized catalyst. In addition, SEM, EDS, and TGA characterization of prepared catalysts and the kinetics behavior of hydrogen evolution were also investigated. Boric acid (H3BO3) was found to be the major product after hydrolysis reaction of ammonia borane via XRD, FT-IR, and NMR analyses. Furthermore, the kinetic curve of hydrogen production from hydrolysis of ammonia borane was calculated to be first order reaction with Co- and Ru-based catalysts. The activation energy in hydrolysis reaction of ammonia borane was observed to be 66 kJ mol-1 and 78kJ mol-1 while Co and Ru catalysts were utilized, respectively.
