Ruthenium‐Based Binary Alloy with Oxide Nanosheath for Highly Efficient and Stable Oxygen Evolution Reaction in Acidic Media

Abstract
Abstract Traditional noble metal oxide, such as RuO 2 , is considered a benchmark catalyst for acidic oxygen evolution reaction (OER). However, its practical application is limited due to sluggish activity and severe electrochemical corrosion. In this study, Ru‐Fe nanoparticles loading on carbon felt (RuFe@CF) is synthesized via an ultrafast Joule heating method as an active and durable OER catalyst in acidic conditions. Remarkably low overpotentials of 188 and 269 mV are achieved at 10 and 100 mA cm −2 , respectively, with a robust stability up to 620 h at 10 mA cm −2 . When used as an anode in a proton exchange membrane water electrolyzer, the catalyst shows more than 250 h of stability at a water‐splitting…
