Outside Back Cover: Sustainable Low‐Valent Iridium Active Sites in Rhenium Doped Perovskite Iridates for Efficient Acidic Oxygen Evolution Reaction via Hybridized Reaction Pathways
Year: 2026
Type: article
Abstract: In a rhenium-doped SrZrxIr1−xO3 perovskite, high-valent Re stabilizes low-valent iridium active sites against overoxidation during acidic oxygen evolution. Dynamic Re–Ir–O interactions open a hybrid adsorbate-evolution/oxide-path mechanism, delivering a 250 mV overpotential, >1,300 A gIr−1 mass activity, and 600 h durability for low-iridium PEM water electrolysis.
