Nonprecious High‐Entropy Chalcogenide Glasses‐Based Electrocatalysts for Efficient and Stable Acidic Oxygen Evolution Reaction in Proton Exchange Membrane Water Electrolysis (Adv. Energy Mater. 35/2023)

Water Electrolysis In 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.
