Abstract
Abstract Engineering nanomaterials at single‐atomic sites can enable unprecedented catalytic properties for broad applications, yet it remains challenging to do so on RuO 2 ‐based electrocatalysts for proton exchange membrane water electrolyzer (PEMWE). Herein, the rational design and construction of Bi‐RuO 2 single‐atom alloy oxide (SAAO) are presented to boost acidic oxygen evolution reaction (OER), via phase engineering a novel hexagonal close packed ( hcp ) RuBi single‐atom alloy. This Bi‐RuO 2 SAAO electrocatalyst exhibits a low overpotential of 192 mV and superb stability over 650 h at 10 mA cm −2 , enabling a practical PEMWE that needs only 1.59 V to reach 1.0 A cm −2 under industrial conditions.…
