Active Motif Change of Ni‐Fe Spinel Oxide by Ir Doping for Highly Durable and Facile Oxygen Evolution Reaction (Adv. Funct. Mater. 1/2023)

Oxygen Evolution Reaction In article number 2209543, Lee, Cho, and co-workers demonstrate that Ir doping (5 mol%) on inverse-spinel NiFe2O4 (Ir-NFO) provides extraordinary activity and robustness for oxygen evolution reaction in alkaline electrolysis. In situ X-ray absorption spectroscopy and density functional theory calculations revealed that the Ir switches the main active reaction center.
