2020
Zou, Xu | Wang, Lina | Ai, Xuan | Chen, Hui | Zou, Xiaoxin
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.
