Diamond electrodes for electrochemical analysis
- 629 Downloads
Conductive boron-doped diamond (BDD) is an alternative to traditional carbon electrodes that provides superior chemical and dimensional stability, low background currents, and a very wide potential window of water stability. Recently, electrochemical applications using BDD electrodes are attracting much attention in many fields, not only in electrochemistry but also in fields such as functional materials science, analytical chemistry, environmental science, biomedical or biological science and so on [1, 2, 3, 4, 5]. In fact, waste water treatment systems, ozone or fluorine generation systems, using BDD electrodes have already become commercially available, and the number of publications involving BDD electrochemistry research is drastically increasing year by year.
In this paper, several examples of electroanalytical applications using polycrystalline BDD electrodes will be shown. Furthermore, some examples using modified functional BDD electrodes such as ion-implanted...
