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.
