Abstract: The oxygen evolution reaction (OER) is an essential half-reaction that is relevant to electrochemical energy conversion and hydrogen energy storage. The surface morphology of gas evolving electrodes can influence their efficiency and resulting performance. In this work, we demonstrate enhanced performance toward the OER after electrochemical aging for a series of high surface area nickel (Ni) electrocatalysts prepared by scalable, fast bead-blasting techniques.
