Sequential Core–Shell to Alloy Evolution Enables the Structural Stabilization and Catalytic Activation of Solid Oxide Electrolysis Cells (Adv. Funct. Mater. 26/2026)

Sequential Core-Shell to Alloy Catalysts In their Research Article (10.1002/adfm.202525596), Jungdeok Park, Wonyoung Lee, and co-workers present sintering-resistant and spontaneously alloyed NiO@CoO core-shell catalysts fabricated by powder atomic layer deposition. These dual-functional catalysts preserve their fine microstructures by suppressing NiO coarsening and exhibit enhanced hydrogen evolution activity through alloy formation.
