Abstract

(Graph Presented) Greater than the sum of its parts: Hydrogen storage in complex hydrides is accelerated by using the ternary composite 2 LiNH 2/LiBH4/MgH2, which exhibits a "self-catalyzing" reaction pathway that results in faster H 2 desorption, lower desorption temperatures, and suppression of NH3 release in comparison to the constituent binary composites (see diagram). The enhanced properties arise from the incorporation of an ionic liquid phase (Li4BH3H10) and from ancillary-reaction seeding of a reversible H2 storage reaction.
