A Comparison Of Potential Window Amongst Boron-Doped Diamond BDD Electrode And Conventional Electrode Materials
BDD Electrode Has Wider Potential Window
Distinguished for possessing the widest potential window in aqueous solutions, BDD electrodes have a wide electrochemical potential window in both aqueous and non-aqueous media. This is due to the inertness of the diamond surface, which results in high overpotentials for OER and hydrogen evolution.
BDD surpasses conventional electrode materials like gold, platinum, and glassy carbon. This unique trait amplifies its efficacy in electrochemical applications.

Applications ranges of BDD electrode from water treatment to water disinfection, electrochemical analysis, electrochemical surface modification, electrochemical detection. Explore laest advancement and various innovative applications of BDD electrode for its unique properties, features and advantages.
Amongst a vast range of applications, water treatment is the most promising one as these electrode materials are implemented to treatment various types of bio-refractory waste streams, and complex industrial effluents for a long time, thanks to the high oxygen evolution potential, low background current, and robust nature. BDD electrodes, especially when act as anodes, they generate huge amount of powerful oxidizing agents, for instance hydroxyl radicals, can remove heavy metals, ammonium, active pharmaand a wide range of organic compounds, including PFAS, alcohols, total organic carbon(TOC), aldehydes, total ammonia nitrogen (TAN), aromatics, amines, active pharmaceutical intermediates, Chemical oxygen demand (COD), BTEX, phenols, pesticides, coloration, total nitrogen and etc, from wastewater. Water disinfection is a critical application of boron doped diamond electrode as it has higher overpotential for oxygen and hydrogen evolutions, which expedite electrochemical ozone production through water electrolysis. Ozone is one of the most powerful oxidizing agents, disinfection could be done in an eco-friendly manner as there will be no addition of chemicals, and no harmful chemical left. Boromond team have developed BDD Ozone generator, for application in food sanitization, home appliances, and swimming pool & spa disinfection.
BDD electrode has much larger potential window means there will be no significant undesired side reactions happen on the surface of BDD electrode once electrical potential applied, lower background current expedites electron transfer rate, enhances sensitivity, and improve detection reliability.
