Abstract

The electrodeposition of copper, gold, nickel, palladium and platinum onto Ebonex® ceramic cathodes has been studied. It is demonstrated that good quality deposits may be obtained and that the kinetics of the deposition and dissolution of metals are similar at Ebonex® to other common substrates (for example, Pt, C). In addition, the kinetics of some simple redox couples at coated and bare Ebonex® ceramic electrodes are compared; it is confirmed that such electron transfer reactions are very slow on the bare Ebonex® ceramic but when the surface is coated with a metal, the kinetics are similar to those on the bulk metal.
