Crystal phase-dependent electrocatalytic hydrogen evolution performance of ruthenium–boron intermetallics

Author affiliations

Abstract

Four crystal phases of ruthenium–boron intermetallics, including Ru7B3, RuB, Ru2B3 and RuB2, are selectively synthesized. With the increase in boron content for the ruthenium–boron intermetallics, Ru–B hybridization interactions decrease. And their hydrogen-evolution electrocatalytic performances are compared, with those of RuB2 exhibiting the best electrocatalytic activity and stability.
