Monodispersed PtNi nanoparticles deposited on diamine-alkalized graphene for highly efficient dehydrogenation of hydrous hydrazine at room temperature

Abstract

Monodispersed PtNi nanoparticles (diameter ≤ 2.5 nm) were successfully immobilized on diamine-alkalized reduced graphene oxide, which exhibited a high activity (turnover frequency, 903 h⁻¹at 303 K) for the catalytic dehydrogenation of hydrous hydrazine.
