Abstract

at overpotentials of 390 mV and 530 mV, respectively, for the oxygen evolution reaction (OER) and hydrogen evolution reaction (HER). In a two-electrode arrangement, the assembled NF(Fe,P)//NF(Fe,P,S) cell showed a very high durability for 3000 h under ampere-level current density. The post-reaction characterization and electrochemical analyses reveal that the incorporation of polyionic species promotes favorable kinetics and suppresses chloride-induced degradation, resulting in high performance and long-term durability.
