ZIF-67-derived Co–N–C supported nickel cobalt sulfide as a bifunctional electrocatalyst for sustainable hydrogen production via alkaline electrolysis

Abstract

This study introduces two efficient electrode materials, NF@ZIF-67@NiCo2S4 and NF@Co–N–C@NiCo2S4, for H2 production, achieving excellent OER, HER and overall water splitting activities with remarkable durability in an alkaline electrolyzer.
