Potential-Dependent Reversible Restructuring of Pt-Au Alloy Electrocatalysts.
The distribution of metals in alloy nanoparticles is a key parameter in their electrochemical performance. Here, we show that for Pt-Au alloys this distribution dynamically responds to the electrochemical environment. Using electrochemical X-ray photoelectron spectroscopy, we find that the surface composition of the al...
