Ultrafine monodisperse bimetallic NiPt nanoparticles with different compositions have been successfully synthesized by coreduction of nickel acetylacetonate and platinum acetylacetonate with borane-tert-butylamine in oleylamine. Among all the catalysts tested, Ni84Pt16/graphene exhibited 100% hydrogen selectivity, and marked high catalytic activity, with TOF values of 415 h(1) at 50 degrees C, and 133 h(1) at 25 degrees C for hydrogen generation from alkaline solution of hydrazine.
