Description
Summary:Water ElectrolysisIn article number 2301420, Jung Inn Sohn, and co‐workers develop nonprecious high‐entropy chalcogenide glasses (N‐HECGs) on carbon paper. The incorporation of Te into a high‐entropy system results in an amorphous, porous structure for the arrayed nanosheet with abundant high valence active sites. N‐HECGs demonstrate promising acidic oxygen evolution reaction performance and stability under practically high current density operation in proton exchange membrane water electrolysis.
