An ultrasmall Ru₂P nanoparticles–reduced graphene oxide hybrid: an efficient electrocatalyst for NH₃ synthesis under ambient conditions

Abstract

A Ru₂P–reduced graphene oxide hybrid acts as a superior catalyst for electrochemical N₂ fixation in 0.1 M HCl, achieving a large NH₃ yield of 32.8 μg h⁻¹mg_cat.⁻¹ and a high faradaic efficiency of 13.04%−0.05 V <italic>vs.</italic> the reversible hydrogen electrode.
