Dual Electronic and Structural Engineering of Ni–Fe Alloys via Molten Salt Electrodeposition for Enhanced Oxygen Evolution Reaction (Adv. Funct. Mater. 8/2026)

Enhanced Oxygen Evolution Reaction This cover artwork vividly illustrates the defect-engineered Ni-Fe alloy catalyst fabricated through innovative molten salt electrodeposition. The 3D porous structure symbolizes efficient mass transport channels, while the dynamic electrical arcs depict ultrafast electron transfer facilitated by artificially designed dislocations and twins. Surrounding water molecules and evolving oxygen bubbles depict the efficient electrocatalytic environment. The imagery encapsulates how simultaneous electronic and structural engineering endows the electrode with exceptional OER activity, providing a unified approach for designing advanced self-supporting electrodes.
