Pure Polycrystalline Boron-Doped Diamond (BDD)
Boron-doped diamond (BDD) is a specialized diamond material created by incorporating boron during the diamond growth process. BDD electrodes, fabricated through chemical vapor deposition (CVD), utilize boron-doped diamond film as the anode with titanium or similar materials as the cathode.
The unique sp3 bond structure of BDD film provides exceptional electrochemical properties including:
- Extremely high oxygen evolution potential
- Widest electrochemical window available
- Lower background current compared to alternatives
- Superior physical and chemical stability
- Low adsorption characteristics

- Excellent biocompatibility (sp3 hybridized structure)
Applications
BDD electrodes demonstrate superior efficiency and lower energy consumption in organic degradation compared to conventional electrodes. Primary applications include:
- Treatment of organic wastewater in pharmaceutical, agrochemical, and petrochemical industries
- Coking, smelting, printing, dyeing, and paper manufacturing processes
- Tanning, explosives production, and landfill leachate treatment
- Electrochemical sensors and biosensors development
- Energy storage, electrocatalysis, and electrosynthesis applications
Important Note: The two larger surfaces exhibit different properties due to postprocessing. While one surface is polished, the other undergoes laser cutting before polishing, affecting boron doping levels and conductivity. Chemical etching is recommended prior to use for optimal performance.
