Boron-doped diamond (BDD) electrodes represent one of the most advanced electrochemical materials available today, distinguished by their unique combination of extreme chemical stability, wide electrochemical potential window, and exceptional durability. These intrinsic properties make BDD a critical and often irreplaceable solution across multiple high-value application fields.
In electrochemical ozone generation, BDD electrodes demonstrate ozone production efficiencies significantly higher than conventional materials. With an oxygen overpotential exceeding 2.3 V and a water electrolysis window of up to 3.5 V, BDD enables ozone concentrations above 20–30 wt%, compared to less than 5 wt% for traditional dielectric methods. This allows compact, on-site ozone systems with lower energy consumption and superior operational safety, widely used in air disinfection, semiconductor manufacturing, and pharmaceutical environments.
For disinfection and sterilization, BDD electrodes generate highly reactive species such as hydroxyl radicals (•OH) with oxidation potentials up to 2.8 V vs. SHE, surpassing chlorine and ozone. This enables rapid inactivation of bacteria, viruses, and spores without chemical residues. In controlled tests, BDD-based electrochemical disinfection systems have achieved >99.99% microbial reduction within minutes, making them ideal for cleanrooms, food processing, and healthcare facilities.
In the field of medical devices, BDD’s biocompatibility, corrosion resistance, and long-term electrochemical stability allow reliable operation under repeated sterilization cycles. BDD coatings are increasingly applied in implantable electrodes, surgical tools, and electrochemical therapy systems, where material degradation is unacceptable.
BDD is also a gold standard for electrochemical sensors. Its ultra-low background current, minimal fouling, and high signal-to-noise ratio enable precise detection of trace-level compounds (down to ppb concentrations) in medical diagnostics, industrial monitoring, and environmental sensing.
With a service life often exceeding 10–20 times that of conventional electrodes, BDD is not merely an alternative material—it is a foundational technology enabling performance levels that other materials cannot achieve.
