Definitions
- the application relates to an electrode based on plastic, which contains conductive diamonds at least on its surface.
- Intrinsic conductivity for example, polypyrrole or polyacetylene.
- such electrodes generally have only a low resistance.
- Conductive plastics are often made by adding conductive substances such as carbon
- conductive diamonds are usually
- Diamond electrodes therefore have an electrochemical window that goes far beyond the decomposition voltage of water, i.e. above 1.23V.
- diamond electrodes can be used for a variety of electrode reactions
- Hydrogen electrode or more positive than the potential of the reversible oxygen electrode Hydrogen electrode or more positive than the potential of the reversible oxygen electrode.
- Negative electrode potentials o Separation of base metals o Separation of heavy metals from highly diluted solutions (e.g. waste water, sludges etc.) o General electrochemical reduction anorg. or organic compounds
- diamond electrodes are mainly produced by CVD coating of metallic or semiconducting substrates with synthetic diamond and subsequent doping with boron.
- these coatings have various technical disadvantages.
- such layers tend to form cracks, as a result of which the exposed substrate material is exposed to the attack, possibly under attack, from very corrosive solutions and positive electrode potentials.
- many metallic substrates cause an undesirable reaction of the carbon with the metal to form metal carbides.
- the electrode according to the invention is preferably made of non-conductive plastics such as
- Metal oxides such as PbO 2 , MnO 2 etc., and on the other hand produced by adding conductive diamond.
- the electrodes can preferably be used in a bipolar arrangement.
- the electrodes are to be designed in a multilayer structure with a metallic core or as metal collectors coated on one side with conductive plastic.
- Diamond can be added both in the entire volume of the electrode material with or without the addition of other conductive components (e.g. carbon black), or only in layers or films with a conductive core near the surface on both sides:
- This core can be made of metal as well as of conductive plastic with little or no
- Diamond content can be formed.
- the electrodes according to the invention have decisive advantages over previous diamond electrodes: • Mechanical stability and flexibility • Corrosion resistance • Non-conductive plastic parts are electrochemically inactive, i.e. no narrowing of the electrochemical window • low weight • cost advantages (material, manufacturing process)
