Abstract

Heavily boron-doped diamond (BDD) has drawn attention as a functional electrode material that exhibits unique electrochemical properties such as wide potential window and low background current. A BDD electrode is usually fabricated by depositing a polycrystalline BDD thin film on a flat substrate, such as a silicon wafer, using the chemical vapor deposition (CVD) method. However, processing a BDD electrode to form an arbitrary shape is difficult, and it has limited practical applications. In contrast, BDD powder (BDDP) emerges as a promising electrode material for the creation of flexible and inexpensive BDD electrodes; the electrode ink is either painted or printed onto various types of substrates. In addition, the BDDP can be used as an electrode material with a large specific surface area. In this chapter, the preparation of BDDP and its application to printed electrodes and as fuel cell catalyst support is described.
