Electrochemical and photoelectrochemical oxygen evolution reactions by Group X hetero-metal oxides

Architecting the High‐Entropy Oxides on 2D MXene Nanosheets by Rapid Microwave‐Heating Strategy with Robust Photoelectrochemical Oxygen Evolution Performance

“…Similarly, the photoinduced holes can support the oxidation process by creating active oxidizing species, further improving the OER kinetics. [20,21] Consequently, the design of a superior OER electrocatalyst with efficient light-harvesting ability is required to boost OER kinetics and reduce electricity consumption.Recently, high-entropy oxides (HEO) that contain five or more metals have gained considerable interest for energy conversion and storage applications because of their exclusive physiochemical properties, such as their single-phase structure, tunable property, excellent stability, multiplicity of composition, high mixing entropy, nanostructure, and synergistic catalytic effect from multiple metal centers. [22][23][24][25][26] Owing to these remarkable properties, a variety of HEO-based electrocatalysts have been synthesized and exhibited promising OER performances.…”
