By directly doping transition metal boride (NbB 2 , ZrB 2 , and CeB 6 ) nanoparticles with size of less than 10 nm into 2LiBH 4 /MgH 2 composites, a significant catalytic enhancement is achieved. As the representative catalyzed system, the nanoNbB 2 ‐doped composite can release ca. 9.0 wt% H 2 in 15 min and reabsorb ca. 9.0 wt% H 2 in 5 min, which show more than 30 and 20 times faster than undoped system.
