摘要：

The electro-reduction of nitrate ions in acid medium on Pt, Ir and on a 70:30 Pt, Ir alloy was studied by cyclic voltammetry. The alloy has a higher activity than the pure metals, which was interpreted as being due to bifunctional catalysis. Values for activation energies evaluated from the experimental data and Arrhenius plot are discussed. (C) Elsevier Science Ltd.
