Exfoliated Transition Metal Dichalcogenide‐Based Electrocatalysts for Oxygen Evolution Reaction

The oxygen evolution reaction (OER) has proved to be a hard-to-overlook impediment for the development of water splitting devices, metal-air batteries, or photo-electrochemical cells, name but few. Electro- and photo-electrocatalysts, designed using inexpensive materials, that demand low overpotential values smoothly drive OER in either electrolyzer devices proton-exchange membrane as well withstand harsh conditions repetitive cycling, are fervently desired by industry. Transition metal dichalcogenides (TMDs), namely MoS2, WS2, MoSe2 WSe2 main representatives, especially when engineered via exfoliation methods, have been highlighted modular scaffolds electrocatalytic applications, owed their ability intrinsic characteristics fine-tuned. In this review, goal is highlight role exfoliation, means engineering, presenting significant works where these TMDs constitute core part OER-catalyzing nanohybrid systems.
