Corrosive engineering assisted<i>in situ</i>construction of an Fe–Ni-based compound for industrial overall water-splitting under large-current density in alkaline freshwater and seawater media

Abstract

The synthesized flower-like Fe–Ni–O–N presents excellent electrocatalytic performance for OER. The assembled electrolyzer shows remarkable catalytic performance and stability in alkaline freshwater, seawater and industrial conditions (60 °C, 6 M KOH).
