Influence of Nanoconfinement on Reaction Pathways of Complex Metal Hydrides

摘要

Nanoconfmement is receiving increasing interest in the field of energy storage and has been applied to different metal hydride systems in order to improve their properties for hydrogen storage. Modified hydrogen sorption kinetics and thermodynamics of metal hydrides have been achieved by nano size effects. In case of metal complex hydrides, in addition to kinetic limitations, competing side reactions and stable intermediates during de/rehydrogenation processes are obstacles for a practical utilization. The impacts of nanoconfmement on dehydrogenation reaction pathways of the eutectic borohydrides LiBH_4-Mg(BH_4)_2 have been studied in the presented work.
