Anomalous dominated (100) index facet endows ruthenium nanoparticles with accelerated alkaline hydrogen evolution

Abstract

Ruthenium (Ru)-based materials are deemed significantly promising alternatives to supersede platinum (Pt)-based catalysts toward hydrogen evolution reaction (HER), especially under alkaline conditions. Herein, we adopt a gradual substitute method to...

Ultrathin core–shell Au@RuNi nanowires for superior electrocatalytic hydrogen evolution

“…8–11 Ruthenium (Ru), at only 1/3 the price of Pt, demonstrates comparable HER activity, and has been regarded as one of the most promising candidates for the HER. 12–14 Simultaneously, the high oxygen affinity and low energy barrier of Ru contribute to facilitating the dissociation of H 2 O, consequently enhancing the alkaline HER activity. 15,16…”
