Lanthanide Doping and Dual-Site Switching on Amorphous High-Entropy Metallene Oxides Boost Acidic Water Oxidation
. Operando characterizations reveal the changes in electronic configurations and coordination environments of Ru and Ir sites during OER. Theoretical simulations further clarify the adsorbate evolution mechanism and the distinct role of the constituent elements. Specifically, the switching of Ru and activated Ir as primary active sites at low and high potentials, respectively, enhances robustness for oxygen generation.
