Abstract

Abstract : Oxygen Evolution Reaction In article number 2209543, Lee, Cho, and co‐workers demonstrate that Ir doping (5 mol%) on inverse‐spinel NiFe2 O4 (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.
