Ag on NiCo Layered Double Hydroxide as Oxygen Evolution Electrocatalyst for Anion Exchange Membrane Water Electrolyzer Under Large Current Densities

anode. Operando electrochemical impedance spectroscopy results reveal that Ag decoration facilitates active site formation and reduces the OER onset potential compared to NiCo LDH. This study showcases a practical approach to designing highly effective and durable OER electrocatalysts in industrial hydrogen production.
