摘要
The electrodeposition of copper, gold, nickel, palladium and platinum onto Ebonex(R) 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(R) to other common substrates (for example, Pt, C). In addition, the kinetics of some simple redox couples at coated and bare Ebonex(R) ceramic electrodes are compared; it is confirmed that such electron transfer reactions are very slow on the bare Ebonex(R) ceramic but when the surface is coated with a metal, the kinetics are similar to those on the bulk metal.
