Niobium-based BDD Electrode Plate
BDD is the abbreviation of Boron-Doped Diamond. BDD electrodes are made of diamond doped with a small amount of boron and have many excellent properties.
The niobium-based BDD electrode plate has good chemical stability, high electrochemical activity, high conductivity, high mechanical strength, and long service life, making it an ideal electrochemical electrode material.
Advantages:
*High chemical stability: The diamond electrode surface has an inactive sp3 structure, which is very stable and can work stably for a long time in strong corrosive media.
*Wide electrochemical potential window: The diamond surface lacks the necessary sites for adsorption reaction intermediates, which is very important for the reaction. The adsorption capacity of the intermediate is weak, which is not conducive to the realization of multi-step electron transfer. The wider potential window of the doped diamond film, especially the higher oxygen evolution potential, can produce strong oxidizing substances such as hydroxyl radicals with higher efficiency. , hydroxyl free radicals have very high activity and can effectively "catalytically incinerate" organic matter;
BDD electrodes have been widely used in sewage treatment, electrolysis and electrochemical synthesis, as well as detectors and sensors based on electrochemical principles.
Regeneration and recycling of micro-etching liquid for processing circuit boards in the PCB industry (can be extended to the production of sodium persulfate in the chemical industry)
For example, the preparation of sodium persulfate from PCB micro-etching waste
liquid using niobium-based BDD electrode.
