Abstract

The specification describes a process for preparing an oxygen evolution reaction catalyst, comprising the steps of: (i) combining iridium powder and a peroxide salt to produce a powder mixture; (ii) carrying out thermal treatment on the powder mixture; (iii) dissolving the product from (ii) in water to produce a solution; (iv) reducing the pH of the solution from (iii) to affect a precipitation and form a solid and a supernatant; (v) separating the solid from the supernatant; and (vi) drying the solid.
