On-board hydrogen storage system with a 5.5 total system-wt% which enables a 300 mile driving range will be a milestone for the realization of a hydrogen economy. Various hydrogen storage materials have been proposed, and developed to meet the corresponding material based gravimetric target, 9 material weight percent H2 released (mat-wt% H2) which are mapped to the DOE (U.S. Department of Energy) technical targets. Among potential storage materials, ammonia borane (NH3BH3, AB) seems to be the most promising one by virtue of its high gravimetric hydrogen storage capacity, 19.6 wt%. To achieve the storage capacity over 9 mat-wt% H2, AB solid or semi-solid state is suggested to be the best option and it will likely be necessary to develop heterogenous catalyst system to come along. Here, we report the tetraglyme (TG)-mediated, size-controlled synthesis of Palladium nanoparticles (PdNPs). Those PdNPs were easily redispersed in a minimum amount of TG with AB and shown to be highly active catalysts for AB dehydrogenation. Most importantly, TG-mediated PdNPs were applied for the generation of H2 from AB/TG semi-solid state system, and recorded high hydrogen storage system {10.01 mat-wt % H2 [mat-wt % H2 = H2-wt/(AB+TG+PdNPs-wts)]} completing hydrogen release in 30 min at 80 ?C.
