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 ...

Cu─O─Al Interfacial Engineering on Cu Nanowires for Durable CO2 Electroreduction Into Multi‐Carbon Products

Advanced Science, EarlyView.
A Cu nanowire/AlOx core‐shell catalyst is reported for CO2 electroreduction. Acting as a Lewis acid, the AlOx shell not only stabilizes Cu+ species at the Cu─O─Al interface but also creates an alkaline local microenvironment via *OH adsorption. This dual functionality stabilizes the catalyst structure while promoting the C─C coupling process, resulting
