Coadsorbed anions are well-known to influence surface reactivity and dynamics at solid-liquid interfaces. Here we demonstrate that the chemical nature of these spectator species can entirely determine the microscopic dynamic behavior. Quantitative in

The potential dependent surface structure of Pt(111) electrodes in electrochemical environment was studied by in situ crystal truncation rod measurements and in operando grazing incidence small angle X-ray scattering. Determination of the interface s

In-situ surface X-ray diffraction is used to characterize the surface oxides on a Pt(111) surface in 0.1 M HClO4. Detailed analysis at two potentials confirms that the surface restructuring in the initial oxidation stages is consistent with a place e

The influence of the oxygen reduction reaction on the oxidation of Pt(111) is studied by surface X-ray diffraction. The oxygen reduction reaction does not significantly influence the place-exchange process during the initial stages of oxidation and t

The molecular arrangement and surface dynamics of Au (111) electrodes in 1-hexyl-3-methylimidazolium chloride ([HMIm][Cl]) and 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([HMIm][TFSA]) were investigated by in situ high-speed scanni

We report direct observation of the formation of a subsurface species at metal electrodes in liquid electrolytes and of its migration within the solid’s surface layer, below a chemisorbed electrochemical double layer. Using in situ video-rate scann

The surface restructuring of Pt(111) electrodes upon electrochemical oxidation/reduction in 0.1 M HClO4 was studied by in situ grazing-incidence small-angle X-ray scattering and complementary scanning tunneling microscopy measurements. These methods

Electrochemical growth of Pt oxide is important because of its role in the oxygen-reduction reaction (ORR) and in Pt dissolution, which affect the performance and durability of PEM fuel cell Pt electrocatalysts. It has been known for a long time that
