Plasmon‐Promoted Electrochemical Oxygen Evolution Catalysis from Gold Decorated MnO₂ Nanosheets under Green Light

The oxygen evolution reaction (OER) is of great importance for renewable energy conversion and storage; however, the intrinsic process is sluggish and suffers from severe efficiency loss as well as large overpotentials. In this work, with the introduction of the plasmonic effects by design of the Au‐MnO 2 hybrid catalysts, it is demonstrated that this photophysical phenomenon could largely promote the confinement of the outer electrons of Mn...
