Abstract
An electrode for an electrochemical reaction bath has a base body, an active side which is configured to come into contact with the reaction bath, and a passive side which is configured to come into contact with at least one electrical conductor. The passive side includes a doped carbon coating that is preferably less than 5 μm in thickness. Preferably the doped carbon coating is a doped polycrystalline diamond coating in sp3 configuration and is doped with boron.
Claims10
A method for producing an electrode, comprising:
- forming a base body comprising silicon to comprise
- an active side configured to come into contact with a reaction bath, and
- a passive side configured to come into contact with at least one conductor;
- then
- coating the active side of the base body with a doped diamond coating;
- then
- cleaning a surface of the passive side of the base body by
- grinding the surface of the passive side, and
- etching the surface of the passive side;
- and then
- coating the surface of the passive side with a doped carbon coating, wherein an electrode is produced with the doped diamond coating on the active side and the doped carbon coating on the passive side, wherein the doped carbon coating has sufficient electrical conductivity to permit current to operate the electrode, wherein the doped carbon coating is 1 μm to 5 μm thick.
