“…In this process, H 2 gas is produced on the cathode surface, which could be used in situ as a hydrogen donor. Various electrodes such as metals [16,17], binary deposited metals [18], alloys [19], metal complexes [20] and synthetic diamond [21] have been studied in the electroreduction of nitrate. Vooys et al [19] found that Cu-modified Pd electrodes showed higher activity for nitrate reduction than single metal electrodes.…”

Pd-Sn modified activated carbon (Pd-Sn/AC) was prepared by impregnation of Pd and Sn salts onto AC followed by heat treatment. Based on scanning electron microscopy, transmission electron microscopy, and X-ray diffraction analysis, Pd-Sn alloy was highly dispersed on the surface of AC with a atomic ratio of about 4.21. A double electrolysis cell was established and separated via a proton-exchange membrane. In the cathodic cell compartment, the as-prepared Pd-Sn/AC was used as particle electrodes where electrolytic reduction of nitrate was performed. A batch mode study showed that at an applied current of 30 mA with 7.5 g/L catalyst, over 90 % of the nitrate could be reduced in 80 min when the nitrate initial concentration was 24.6 mg/L. The electro-catalytic process of nitrate reduction could be satisfactorily described with a first-order kinetics model. With increasing applied current, the nitrate removal rate increased; whereas, the NH 4 ? concentration increased as well. The inhibition effect of coexisting anions and cations on nitrate reduction followed this order:

“…Products produced by the electrolysis depend on the electrode materials. So, it has been conducted using various electrodes such as metals (Peel et al, 2003;Dima et al, 2003), binary deposited metals (Kerkeni et al, 2002), alloys (Vooys et al, 2000), metal complexes (Gootzen et al, 1999) and synthetic diamonds (Tenne et al, 1993). Vooys et al (2000) found that Cu-modified Pd electrode showed higher activity for nitrate reduction than a single metal.…”

A comparative study of the influence of an addition of Zn to Cu as the basic cathode material on electrocatalytic activity for NO À 3 reduction was performed. Potentiodynamic measurements using a rotating ring-disk electrode were carried out in an artificial solution simulating solution after regeneration of the ion-exchange column for NO À 3 removal in drinking water treatment. The results were verified by batch electrolysis experiments. An enhancement of the electrocatalytic activity was observed. Unfortunately, NH 3 was found to be the main NO À 3 reduction product. The highest electrocatalytic activity was obtained using an electrode containing 41 wt.% Zn.
