Abstract

Abstract : Synthesis of a high performance pH universal electrochemical hydrogen evolution catalyst based on OsP2 . Abstract : The synthesis is described of a pH-universal hydrogen evolution electrocatalyst based on N and P co-doped graphitic carbon encapsulated OsP2 (OsP2 @NPC) nanoparticles of 1.8 nm size for the electrocatalytic hydrogen evolution reaction (HER). Our OsP2 -based catalyst is catalytically active at all pH values and delivers the benchmark current density of 10 mA cm −2 at an overpotential of 46, 90 and 144 mV in acidic, alkaline and neutral pH, respectively.
