摘要

Over the past decade, sodium borohydride (NaBH_4) has been extensively investigated as a potential hydrogen storage material. The development of catalyst materials for on demand NaBH_4 hydrolysis, and the design of practical reaction systems for hydrogen storage based on NaBH_4 are key research areas. Progress in the former area has been promising, with many non-noble catalysts being reported with activities comparable to those of higher-cost noble metal catalysts. However, the design of practical hydrogen storage systems remains a critical issue, as identified by the U.S. Department of Energy (DOE) in their "No-Go" recommendation in 2007. The problems of by-product precipitation and catalyst blockage at high NaBH_4 concentrations must be addressed in order to produce a hydrogen storage system capable of meeting the DOE target of 5.5 wt% H_2 (2015). It is likely that a new, novel reaction system design will be required to achieve these targets, given the limitations identified in conventional systems. Moreover, a new process for regenerating spent NaBH_4 will need to be developed, in order to lower its cost to a viable level for use as a transportation fuel.
