| Research Abstract |
In this study, the relationship between the adsorption states of nitrate on Pd, Pt, and Rh electrodes and the reactivity was reported. The reason for the increase of reactivity of nitrate reduction by Sn modification was also discussed. The results from IR measurements showed that unidentate nitrate was the reactive species. The unidentate nitrate can be easily protonated, which facilitates the cleavage of N-O bonds, and the reduction is carried out. For the electrode modified by Sn, the increase of reactivity of nitrate reduction is given by the interaction between O in the adsorbed nitrate and Sn, which facilitates the cleavage of N-O bonds and the reduction of nitrate.
