Résumé
In article number 1700122, Kondo‐Francois Aguey‐Zinsou and co‐workers demonstrate a novel and simple approach to control the properties of ammonia borane (AB) and investigate the drastic effect of such a strategy on the hydrogen storage properties of AB. Nanosizing AB and further coating with nanosized nickel (Ni) leads to a AB/Ni matrix that enables hydrogen reversibility along the thermal decomposition path of AB. These findings open significant new avenues in the search of high capacity hydrogen storage materials based on light and relatively abundant elements for hydrogen storage on‐board vehicles.
