Wide Potential Window: The electrochemical window refers to the difference between an electrode's oxygen evolution potential and hydrogen evolution potential, serving as a key indicator of an electrode material's electrochemical stability. BDD exhibits a wide electrochemical window (up to 3.5 V), enabling BDD electrodes to undergo electrochemical reactions across a broader potential range. Concurrently, BDD electrodes possess an exceptionally high oxygen evolution potential (approximately +2.5 V), facilitating electrode redox reactions at elevated potentials.
Low Background Current: Due to the low electron density near the sp³ carbon Fermi level on the BDD electrode surface, the double-layer capacitance formed is minimal, resulting in a low background current. BDD electrodes exhibit a higher signal-to-noise ratio in electrochemical detection, thereby enhancing detection sensitivity and accuracy.
Low adsorption characteristics: Diamond exhibits exceptional chemical inertness with minimal adsorption of foreign molecules, resisting contamination and maintaining stable electrochemical response over extended periods.
High stability: BDD electrodes demonstrate outstanding chemical stability, remaining virtually unaffected by conventional electrochemical experiments and exhibiting negligible reaction to corrosive substances like strong acids and bases. This grants them exceptionally long service life and high reusability, making them suitable for demanding conditions.
Biocompatibility: BDD possesses a stable chemical structure, making its surface resistant to erosion or degradation by biological substances. This stability ensures the material maintains its properties within living organisms over extended periods, thereby minimizing potential harm to the host.
