title: Graphene-supported nickel-platinum nanoparticles as efficient catalyst for hydrogen generation from hydrous hydrazine at room temperature.
abstract: 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 °C, and 133 h(-1) at 25 °C for hydrogen generation from alkaline solution of hydrazine.
