Self‐Reconstruction of Dual‐Morphology Copper‐Iron Selenides for Cost‐Effective Oxygen Evolution Toward Industrial Alkaline Water Splitting (Adv. Funct. Mater. 10/2026)

Electrochemical Oxygen Evolution In their Research Article (10.1002/adfm.202522239), Fei Wang, Hua Wei, and co-workers present a dual-morphology CuFe─Se catalyst for the oxygen evolution reaction (OER). During the operation, Cu─Fe charge interference triggers self-reconstruction into a durable SeOx-regulated FeOOH active phase, which offers a promising alternative to conventional Ni/Co-based anodes for industrial alkaline water electrolysis.
