Abstract

Electrochem. and phys. properties of polycryst. B-doped diamond electrodes with a metallic conduction grown by MPCVD and HFCVD were studied with the goal to use them as cathodes, for the electrochem. redn. of nitrate in neutral solns. All electrodes contain a mean B concn. [B] >3 * 1020/cm3 and show a significant redn. of nitrate. However, the higher efficiency is obtained for the electrode having the highest [B] (1.5 * 1021/cm3) and the lowest concn. of parasitic phases. The anal. of the Raman spectrum proved to be a valuable tool to probe these characteristics. Quant. anal. of the solns. showed that the relative concns. of the nitrogenous species formed during the redn. of nitrates at -2 V do not depend on the B doping level. [on SciFinder (R)]

Electrode

An electrode is an electrical conductor used to make contact with a nonmetallic part of a circuit (e.g. a semiconductor, an electrolyte, a vacuum or air). Electrodes are essential parts of batteries that can consist of a variety of materials depending on the type of battery. The electrophore, invented by Johan Wilcke, was an early version of an electrode used to study static electricity. Electrodes are an essential part of any battery. The first electrochemical battery made was devised by Alessandro Volta and was aptly named the Voltaic cell.

Reference electrode

A reference electrode is an electrode that has a stable and well-known electrode potential. The overall chemical reaction taking place in a cell is made up of two independent half-reactions, which describe chemical changes at the two electrodes. To focus on the reaction at the working electrode, the reference electrode is standardized with constant (buffered or saturated) concentrations of each participant of the redox reaction. There are many ways reference electrodes are used.

Doping (semiconductor)

In semiconductor production, doping is the intentional introduction of impurities into an intrinsic semiconductor for the purpose of modulating its electrical, optical and structural properties. The doped material is referred to as an extrinsic semiconductor. Small numbers of dopant atoms can change the ability of a semiconductor to conduct electricity. When on the order of one dopant atom is added per 100 million atoms, the doping is said to be low or light.
