High-Entropy Sulfides as Oxygen Evolution Catalyst for Anion Exchange Membrane Water Electrolyzer

Abstract

A high-entropy sulfide (NiFeCoCrZr)S/C is synthesized via carbothermal shock, which illustrates high oxygen evolution reaction catalytic performance with low overpotential of 271 mV to achieve current density of 100 mA·cm−2 and low potential degradion rate of 94 μV·h−1 over 300 h of test, showcasing the promise of high-entropy materials for water electrolysis anodes.
