Boron-Doped Diamond Coated Niobium Mesh Electrode with Holder
The Boron-Doped Diamond (BDD) Coated Niobium Mesh Electrode is designed for advanced electrochemical oxidation processes (EAOP), wastewater treatment, electrochemical synthesis, and laboratory research. BDD electrodes combine the outstanding conductivity of boron-doped diamond with the excellent corrosion resistance of niobium, providing exceptional durability and high oxidation efficiency in demanding electrochemical environments. They are particularly suitable for applications requiring high anodic potentials and efficient hydroxyl radical generation without the addition of chemical oxidants
This product, in a quantity of 1 piece, is available with a basic sample holder, which works excellently as an electrical contact. It allows for full immersion of the electrode in the electrolyte without the risk of corrosion of the contact made from tantalum. Other contact metals are also available, and the list can be found on another product's page. Please get in touch with us if you wish to replace the tantalum contact with another metal. BDD-coated niobium electrodes are also available without the holder. Make sure you select the correct option when applying for a quote.
Application note
Boron-Doped Diamond (BDD) coated niobium mesh electrodes are designed for electrochemical processes that require high oxidation efficiency, exceptional chemical stability, and long service life. Their ability to generate hydroxyl radicals directly from water makes them particularly effective in Electrochemical Advanced Oxidation Processes (EAOP), where contaminants can be degraded without the addition of chemical oxidants.
In environmental applications, BDD electrodes are widely used for the treatment of industrial and municipal wastewater containing persistent organic pollutants. They are especially suitable for research and pilot-scale systems focused on the degradation of PFAS, pharmaceutical residues, dyes, pesticides, endocrine-disrupting compounds, and other contaminants that are difficult to remove using conventional treatment methods.
The excellent electrochemical properties of boron-doped diamond also make these electrodes valuable tools for laboratory research and electrochemical process development. They are commonly used in studies involving electroorganic synthesis, electrocatalysis, green chemistry, advanced oxidation mechanisms, and the development of new electrochemical reactors.
Beyond water treatment, BDD electrodes are employed in materials science, corrosion research, sensor development, semiconductor research, and other applications where a chemically inert, highly stable, and reproducible electrode material is required. Their robust performance under demanding operating conditions makes them suitable for both fundamental research and industrial process optimization.

material composition (Raman)
The Raman spectrum exhibits the characteristic features of boron-doped diamond, including the boron-related bands around 500 and 1200 cm⁻¹ together with the diamond phonon peak near 1332 cm⁻¹. The relatively weak G band indicates a low content of sp² carbon, confirming the formation of a high-quality boron-doped diamond coating suitable for electrochemical applications.
electrochemical characterization
This report compares the electrochemical performance of three boron-doped diamond (BDD) electrode materials offered by redox.me: a BDD plate, BDD on a silicon substrate, and BDD-coated niobium mesh. The materials were evaluated in terms of their electrochemical potential window and electron-transfer kinetics using cyclic voltammetry. The results demonstrate that all investigated electrodes exhibit high electrochemical quality, while electrochemical cleaning significantly improves the performance of the BDD-coated niobium mesh and silicon substrate. The findings provide guidance for selecting the most suitable BDD electrode for analytical, sensing, and advanced oxidation applications.
