Nitrate Reduction at Tin-modified Noble Metal Single Crystalline Electrodes

Abstract

Electrocatalytic denitrification is one of the most environmentally friendly approaches to remove nitrate ions from groundwater. Polycrystalline Pt and Pd electrodes modified with tin are known to show high activity in electrocatalytic nitrate reduction. In this study, we have prepared Sn-modified Pt, Pd and Pd-Pt alloy single crystalline electrodes and investigated the relationship between the electrode surface structure and nitrate reduction activity.
