Abstract

The electrochemical activity of surface conductive diamond in aqueous media has been investigated for two redox systems, the reduction of Ru (NH ₃)₆³⁺ to Ru (NH₃)₆ ²⁺ and the reduction of Ag⁺ to Ag. Although electrochemical activity is observed, the responses are not as well defined as at conventional boron-doped electrodes, and in particular, poor long term stability is exhibited. This is attributed to a degradation of the electronic properties of the surface conductive phase as a result of the electrochemical reactions themselves, which tend to disrupt chemically the surface hydrogen layer required for surface conductivity, Electroless deposition of Ag is also observed, as a result of the unusual electronic and chemical properlies of surface conducting diamond.
