We have proved previously, that reaction between LiBH4 and MgH2 can indeed occur during ball milling with aerosol spraying at room temperature. In this study, the nanoscale MgH2 + LiBH4 mixtures are obtained by ball milling with aerosol spraying under ice-water cooling system (0℃). The amount of H2 released in the solid state from 25 to 265℃ reaches 3.88 wt.%, which is substantially higher than 0.75 wt.% and 0.1 wt.% H2 released by bulk LiBH4 and MgH2, respectively. Hydrogen uptake, although slower than release, can also reach 3.78 wt.% in solid state. All of these enhancements are achieved without any catalysts, which underscores the effectiveness of nanoengineering and mechanical activation as well as the opportunity for future improvements in the future.
