Abstract
Developing active, stable, and cost-effective acidic oxygen evolution reaction (OER) catalyst is a critical challenge in realizing large-scale hydrogen (H2) production via electrochemical water splitting. Utilizing highly active and relatively inexpensive Ru is generally challenged by its long-term durability issue. Here, we explore the potential of stabilizing active Ru sites in Rux(Ir,Fe,Co,Ni)1–x multicomponent alloy by investigating its phase formation behavior, OER performance, and OER-induced surface reconstruction. The alloy exhibited a multiphase structure composed of major face-centered cubic (fcc) and minor hexagonal close-packed (hcp) phases at near equimolar concentration. Machine-learned…
