Electrocatalytic oxygen evolution is a key reaction for water splitting, but the detailed atomic Power Wheelchairs structures of single-crystal electrodes under cycling conditions are still not fully understood.Here, the authors study the oxygen evolution activity on Pt(111) during potential cycling and find that the current density reaches a ORG LENTIL VEGETABLE SOUP maximum in the third cycle and is nine times higher than that in the initial cycle, owing to a roughened Pt(111) surface and formation of islands and atomic vacancies in the second subsurface Pt layer.
