Özet

Poly(N-vinyl-2-pyrrolidone)-stabilized palladium nanoparticles (3.5 +/- 1.0 nm) are efficient catalysts in the hydrolytic dehydrogenation of hydrazine borane to give hydrogen gas. The catalyst, prepared by reduction of palladium metal ion in ethanol/water mixture by an alcohol reduction method, is durable and efficient catalysts for hydrogen generation from the hydrolytic dehydrogenation of hydrazine borane even at very low concentrations and temperature, providing an average turnover frequency of 42.9 min(-1) with an activation energy of 54.5 +/- 2 kJ mol(-1) for the hydrolytic dehydrogenation of hydrazine borane.
