Boron-doped diamond (BDD) is a new type of diamond formed by adding boron in the process of diamond growth. Electrodes made of boron-containing diamond are also called BDD electrodes or boron-doped diamond electrodes. BDD electrodes are usually made into thin films by chemical vapor deposition (CVD).
The BDD electrode uses boron-doped diamond film as the electrode anode, and titanium or other materials as the cathode for electrolysis. The special sp3 bond structure of boron-doped diamond film and its electrical conductivity give the diamond film electrode excellent electrochemical characteristics, extremely high oxygen evolution potential and widest electrochemical window, lower background current, and better physical and chemical stability and low adsorption characteristics. It is an ideal anode material for electrochemical oxidation treatment of hard-to-biodegrade organic wastewater.

| Key product features: | BDD is a semi-metallic material characterized by high conductivity and fast electron transfer. BDD electrodes are recognized as being superior to other electrode materials due to excellent electrochemical properties. Main advantages include: (i) outstanding chemical and dimensional stability, (ii) exceptionally low background current, (iii) an extremely wide potential window for water electrolysis, (iv) a broad electromagnetic transparency window of thin films ranging from the UV-Vis region to the far-infrared region, (v) low magnetic susceptibility compared to other electrode materials, and (vi) excellent biocompatibility (sp3 hybridized structure). |
| Key product features: | Under the same conditions, the efficiency and energy consumption of BDD electrodes in degrading organics are significantly better than other electrodes. |
| Application | various organic waste water, such as organic waste water in the fields of medicine /agrochemicals,petrochemicals, coking, smelting, printing and dyeing,papermaking, tanning, explosives, wine making, landfill leachate, etc. |
| Application note | Properties of BDD are particularly important in electroanalysis for the development of sensors and biosensors. BDD electrodes allow to detect many electroactive molecules in aqueous media that would otherwise be masked by water decomposition reactions at higher potentials. The surface of BDD electrode can be further (photo)functionalized or decorated. In order to enhance the electrochemical response in a presence of organic molecules, the surface of BDD can be also modified with metal nanoparticles (e.g. Au). BDD is also a broadly used electrode material for electrochemical energy storage, electrocatalysis or electrosynthesis. Please note that two larger surfaces have non-equal properties. This is a consequence of postprocessing of BDD polycrystal. While one surface is just polished the second is first laser cut and then polished. The temperature released during the laser cut affects the level of boron doping and in consequence decrease the conductivity. Chemical etching is recommended before use. |
