Use of boron-doped diamond electrode in ozone generation

摘要

Highly boron-doped diamond (BDD) electrode was used as anode for ozone generation system by electrolysis of acidic solution. We have succeeded to generate ozone by using this BDD electrode with high efficiency compared to traditional lead oxide (PbO2) electrode. Ozone generation by using PbO2 electrode was gradually decreased due to its structural degradation at continous operating. However electrochemical and physical properties of the BDD electrode were kept its high stability even after long operation time (>3000 hours) in comparison with PbO2 electrode. The stability of BDD electrode for longtime operation was due to physical and chemical properties of diamond electrode. It was expected that the use of BDD electrode as an anode would make a positive contribution to the electrochemical ozone generation.
