Monodisperse nickel nanoparticles and their catalysis in hydrolytic dehydrogenation of ammonia borane

The synthesis of monodisperse Ni nanoparticles which exhibited high catalytic activity in hydrogen generation from the hydrolysis of the ammonia-borane (H3NBH3) complex is reported. The Ni nanoparticle catalysis supported on the Ketjen carbon support represent a promising route for the practical development of the [H.sub.3]NB[H.sub.3] complex as a feasible hydrogen storage medium for fuel cell applications.
