Abstract
The present invention provides a simple method for producing an electrode having improved oxygen evolution reaction (OER) activity without a need for catalyst coating and an electrode produced by this production method. The method is a method for producing an electrode including a step of subjecting an electrically conductive substrate comprising a nickel alloy comprising 30 to 70% by mass of Ni and 30 to 70% by mass of Fe, provided that Ni+Fi=100% by mass, to a thermal treatment, and a step of etching the thermally treated electrically conductive substrate with an etchant comprising at least any acid of an organic acid and a weak inorganic acid. The electrode is an electrode that is produced by this production method and that is useful as an oxygen evolution anode or the like.
