Abstract

Uniform ruthenium phosphide (Ru₂P and RuP) nanocrystals grown in situ on N- and P-codoped graphene were obtained by pyrolyzing tris(triphenylphosphine) ruthenium(II) chloride (TPP-Ru) with pyritic acid (PA). Interestingly, Ru₂P and RuP can be controllably prepared by varying the molar ratio of PA to TPP-Ru. As an efficient electrocatalyst for the hydrogen evolution reaction (HER), Ru₂P exhibited a better performance than RuP in alkaline medium.
