This study details a “wet” atomic layer deposition process that uses potential modulation and H adsorption to terminate Ir deposition at high deposition overpotentials. The ultrathin Ir films match or exceed the best reported electrocatalytic activity for the oxygen evolution reaction (OER) and hydrogen production and oxidation reaction (HER and HOR) on bulk Ir electrodes.
