Metal Nanoparticles‐Catalyzed Hydrogen Generation from Ammonia Borane

Ammonia borane (AB), a promising chemical hydrogen storage material, has attracted much attention due to its high stability, low molecular weight, and high hydrogen density. In the past decade, numerous highly active metal nanoparticles (NPs) based catalysts have been developed for the hydrolysis and methanolysis of AB to produce hydrogen. This chapter reviews the recent advances in monometallic and heterometallic NPs catalysts with excellent catalytic activity and recyclability toward AB hydrolysis and methanolysis. We also survey the corresponding mechanism of hydrogen production during hydrolysis and methanolysis as well as the regeneration methods for AB. At last, the merits and demerits of AB solvolysis are discussed.
