5_07/2013Cover Picture: Electrocatalytic Reduction of Nitrate on a Pt Electrode Modified by p-Block Metal Adatoms in Acid Solution (ChemCatChem 7/2013)

Tin soldiers The cover picture shows the interaction of nitrate with a tin-covered platinum surface in an aqueous electrolyte. In their Full Paper on p. 1773 ff., 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.
