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.
Model: | a cvd polycrystalline Boron-Doped Diamond (BDD) |
| Crystal growth process: | cvd Boron-doped |
| Color: | black |
| Shape: | Circle ,Square,triangle |
| Size range: | 2-50mm,thickness:0.1-0.5-1.0mm |
| 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. |
