Why Choose Boron Doped DIAMOND Electrode Over Mixed Metal Oxide Electrode
A Comparison Between MMO and Boron Doped Diamond Electrodes
To explore the differences between boron doped diamond electrode and mixed metal oxide (MMO) electrode as the next-gen electrode material for multiple electorchemical applications, in aspects such as dimensional & chemical stability, electrochemical potential window, background current, electrchemical efficiency and organic oxidation. Boron doped diamond (BDD) electrodes exhibit a spectrum of exceptional properties, distinguishing themselves as unparalleled in the realm of electrochemistry. Their standout features include an impressively expansive potential window, surpassing that of any other electrode material. Particularly noteworthy is their prowess in anodic potentials, setting a new standard for electrochemical exploration. Moreover, BDD electrodes boast remarkably low background and capacitive currents, underscoring their efficiency in various applications. Compared to conventional MMO/DSA electrodes, they showcase reduced fouling, ensuring prolonged and consistent performance, making them a top choice for industries seeking reliability and precision.
Chemical Stability One of the standout characteristics of boron doped diamond electrodes is their exceptional chemical stability. It’s virtually impervious to corrosion, which makes it an ideal choice for applications where exposure to harsh chemicals is a constant concern. Boron-doped diamond is almost entirely chemically inert, meaning it won’t react with most chemicals, which makes boron doped diamond electrode an ideal anode material for applications involving strong acids, bases, and aggressive compounds, making these electrodes the prime choice in wastewater treatment toward industries such as lithium battery production/recycling, gas & petroleum and pharmecutical. MMO electrodes exhibit resistance to corrosion and can withstand various chemical environments. However, prolonged exposure to exceedingly aggressive conditions might cause a gradual decline in their performance. BDD electrodes triumph over MMO electrodes in terms of chemical stability, showcasing exceptional resistance to a broad spectrum of chemicals and thriving in even the harshest conditions. While MMO electrodes display good corrosion resistance, they may require more attention to uphold their longevity in extremely harsh environments.
Remarkable Low Background Current
The reduced background current associated with diamond electrodes not only enhances sensitivity but also lowers detection limits, making it an ideal choice for cutting-edge research. This exceptional material has sparked considerable interest in the scientific community, thanks to its unique properties that enable groundbreaking research and experimentation.Boron-doped diamond electrodes perform better than conventional MMO electrodes under stronger current density and higher pH.
Dimensional Stability BDD electrodes exhibit an extraordinary level of dimensional stability, remaining virtually unaltered in physical structure even during prolonged use. BDD boasts a low coefficient of thermal expansion (CTE) close to zero, meaning it does not expand or contract significantly with changes in temperature. This property is invaluable in high-precision equipment and electronics, as it minimizes the risk of thermal stress-induced damage.This outstanding attribute is pivotal for applications requiring consistent and enduring electrode performance over extended periods. MMO electrodes offer satisfactory dimensional stability, although not reaching the extraordinary level demonstrated by BDD electrodes. They are suitable for prolonged use but may require more frequent maintenance to ensure consistent performance.
Electrochemical Potential Window
BDD electrodes have the largest electrochemical potential window in aqueous solutions compared to traditional electrodes like gold, platinum etc,. Traditionally, electrode surfaces like gold (Au) and platinum (Pt) limited the analysis of reactions to certain potential ranges. However Boron-doped diamond (BDD) electrodes are a game-changer in electrochemical analysis experiment, offering an expansive potential window in aqueous solutions and impressively low background currents. Testing results indicated reactions occurring in potential ranges spanning from approximately -0.4V to -1.3V and about +1.7V to 2.6V.
Boron doped diamond (BDD) electrode is one of the non-active electrode materials with highest oxygen evolution overpotential thanks to the unique SP3 structure. Boron doped diamond electrode requires larger potential to initiate the oxygen evolution reaction, making it ideal for electrochemical applications requires high rate of oxidation/redox reaction but yet no side reactions, the OER advantages of this electrode material are accomplished via its exceptional chemical and dimensional stability and wider potential window.
Oxygen evolution overpotential (V vs. SHE) comparison between conventional electrode materials and boron doped diamond electrode demonstrated that Titainium/Boron doped diamond electrode performed much higher oxygen evolution overpotential and oxidation power than MMO electrode and conventional electrode material.
Hydroxyl radicals can be electrochemically generated on the surface of boron doped diamond electrode once electric current and potential applied, check electrolysis process via boron doped diamond electrodes here, the electrolysis processes dismantling H2O to generate hydrogen atom and oxygen, combined to form hydroxyl radicals. Hydroxyl radicals are the second most active oxidizing agents. Hydroxyl radicals react rapidly with many organic compounds through series of interaction. They performed strong chemical deterioration and released constant organic molecules mineralization, breaking these compounds into carbon dioxide, water, and etc.
