AN INEXPENSIVE AND ROBUST OXYGEN EVOLUTION ELECTRODE

摘要

An electrochemical device includes an electrolyte, a cathode contacting the electrolyte, and an oxygen evolution reaction (OER) electrode operating as an anode contacting the electrolyte. The OER electrode includes an iron-containing substrate and a layer that includes a metal-containing layer disposed over the iron-containing substrate. The metal-containing layer includes a metal and iron, the metal being selected from the group consisting of nickel, cobalt, manganese, and combinations thereof.
