Stretching exercises: The electrochemical behavior of pseudomorphic palladium monolayers (PdML) on various single-crystal electrodes is investigated (see picture) to demonstrate the influence of lateral compression and dilation on surface activity. The adsorption behavior and the catalytic activity for formic acid electrooxidation varies dramatically depending on whether the palladium monolayer is compressed or dilated by the single-crystal electrode.
