MOx/Rh Metallene with Energetic Interfaces as Efficient Bifunctional Electrocatalyst for Durable Water Splitting

Advanced Science, EarlyView.
 . ABSTRACT Developing excellent activity and stability bifunctional electrocatalysts for alkaline water splitting remains challenging. This work constructs ultrathin MOx/Rh metallene heterostructures (M = Fe, Co, Ni) via atmosphere‐controlled solvothermal synthesis, achieving uniform MOx nanoclusters on Rh metallene with optimized interfaces. The FeOx/

A Perspective on the Applications of Triphasic Gas Storage in Electrochemical Systems

Advanced Science, EarlyView.
Gas storage in microporous materials positioned locally at an electrode or electrocatalyst surface enhances electrochemical processes. Abstract Microporous materials store gases under dry conditions (e.g., hydrogen or oxygen via physisorption), but in some cases microporous materials also show triphasic (e.g., in a solid|gas|liquid system) gas storage ...
