    ABSTRACT: Here, we present that transition metal(0) nanoparticles can be employed as highly active, long-lived and reusable catalyst in hydrogen generation from the boron based hydrogen storage materials for fuel cell applications. Transition metal(0) nanoparticles were prepared from the reduction of respective precursor in the presence of anionic or polymeric stabilizer. All the transition metal(0) nanoparticles (Fe, Co, Ni, Ru) prepared show very high catalytic activity in hydrogen generation from the hydrolysis of sodium borohydride or ammonia-borane at room temperature. Rhodium(0) nanoparticles stabilized by tert-butylammonium octanoate or dimethylammonium hexanoate are superb catalyst in dehydrogenation of ammonia-borane or dimethylamine borane at room temperature, respectively. Further enhancement in catalytic activity could be achieved by preparing transition metal(0) nanoclusters within supercages of zeolite-Y. Zeolite stabilized cobalt(0), nickel(0), ruthenium(0), and rhodium(0) nanoclusters are very active catalyst in hydrogen generation from the hydrolysis of sodium borohydride or ammonia-borane at room temperature.
