A simple electrochemical process named electrochemical atomic layer deposition (EALD) is presented. The H passivation layer inhibit the further reduction of metal ions in electrolyte at highly negative overpotential. However, the surface of electrode can be reactivated by pulsing the potential to more positive values where the adsorbed H is oxidized. Interestingly, with the repeated pulses, the layer-by-layer structure can be obtained by the simple EALD process. The catalytic activity of ultrathin film electrocatalyst match or exceed the best activity recently reported in fuel cell and water splitting reactions. |
