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.
