Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>Tin soldiers</bold> The cover picture shows the interaction of nitrate with a tin‐covered platinum surface in an aqueous electrolyte. In their Full Paper on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">p. 1773 ff., </ext-link> J. Yang et al. study a wide range of promoters for the electrocatalytic reduction of nitrate, a reaction of importance in industry and the environmental remediation of nitrate‐laden waste water. Of all the p‐block elements, tin outperforms as the most active promoter. First‐principles DFT calculations suggest that the hydroxylated surface‐adsorbed tin atoms promote nitrate reduction most efficiently by enhancing the bonding of nitrate to the platinum–tin surface.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg22f4zj4m" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
