Boron-Doped Diamond Solutions

Our disk electrodes offer superior electrochemical performance to other commercially available electrodes. These electrodes embed a 2mm polished BDD disk in a 6cm long x 6mm outer diameter PEEK housing. Custom orders with other chemical resistant housings, including PTFE, are possible. Each electrode comes with a silicon O-ring for varable depth in an electrochemical cell. A silicon electrode end-cap is also included for proper storage when not in use.

With a lower capacitive background current and wider potential window to other competing electrode materials such as glassy carbon (GC), Fraunhofer USA CMW BDD disk electrodes can be used for electroanalytical measurements with ease. As seen (above or below), many electrode materials including GC exhibit background voltammetric peaks that can potentially mask analyte current measurements. This is not observed on our BDD disk electrodes as flat, featureless background currents are measured.

BDD electrodes have the proper combination stability, ruggedness, and lifetime for use in electrochemical oxidation applications, including electrochemical advanced oxidation. These BDD electrodes are fabricated on metal substrates (typically niobium (Nb), tantalum (Ta), or molybdenum (Mo)) for proper mechanical stability.  This includes but is not limited to individual electrode plates, multi-electrode stacks, or metal-stubs for a rotating-disk electrode (RDE) setup. Custom designs and substrates are possible, if desired. 

Our BDD electrodes have shown promise for use in many applications of water treatment. This includes per- and polyfluoroalkyl substance (PFAS) remediation as well as chemical oxygen demand (COD), total organic carbon (TOC), total ammonia nitrogen (TAN), and total nitrogen removal from contaminated water. Electrochemical oxidation processes with BDD electrodes can also work to reduce turbidity of wastewater samples. Fraunhofer USA CMW also has the capability to coat expanded metal mesh and other like-substrates/geometries for water disinfection and electrochemical ozone generation. For all electrochemical oxidation applications, customization of BDD electrodes to fit your experimental needs is often required. More information about PFAS Remediation can be found here.  

Additionally, if you are interested in investigating electrochemical oxidation using BDD electrodes for your water treatment application, we can test your water for you! COD, TOC, TN, and TAN measurements will be completed, but analysis can be customized for your specific needs. 

Combining the advantage of rugged BDD material with optical transparency, our BDD OTEs are excellent tools for spectroelectrochemical measurements. Applications range from the general study of redox chemistry (inorganic, organic, biological molecules) to spectroelectrochemical sensing where excellent sensitivity and selectivity can be obtained.

The BDD films are grown on quartz substrates and exhibit a wide range of optical transparency.  Measurements can be made below 300 nm, a quality certain OTE materials can not achieve The optical and electronic properties can be altered depending on your experimental requirements; a more conductive film will be less optically transparent, while a more optically transparent film will be less conductive. Custom dimensions can be accommodated to fit a specific geometry.

We are also pleased to offer free-standing BDD plates for a variety of applications to fit specific experimental needs. BDD plates exhibit high electrical conductivity that is maintained at elevated temperatures, excellent mechanical and chemical rigidity, and long-lifetime.  BDD plates are as-grown, unpolished, and 400 μm thick. The material is typically offered in 10 mm x 10 mm geometries (picture shown). However, Fraunhofer USA CMW can accommodate other geometries, where desired.
