Ozone is a strong oxidizing agent widely used in wastewater treatment and food sterilization. Currently, electrochemical ozone production is studied in acidic solutions or pure water. However, in pure water system, a membrane electrode assembly (MEA) is usually employed. Research on using tap water as the electrolyte for electrochemical ozone production has received insufficient attention. In this study, a nickel/antimony doped tin oxide catalyst electrode was used for ozone production via electrolysis of tap water without membrane. The maximum ozone current efficiency (4.11%) was achieved at a voltage of 7 V, a water pumping rate of 12 mL/min and temperature of 6 °C. These results demonstrate the feasibility of using a nickel/antimony-doped tin oxide catalyst electrode to produce ozonated tap water, and this study provides support for the practical applications of ozonated tap water.

摘要

Ozone is a strong oxidizing agent widely used in wastewater treatment and food sterilization. Currently, electrochemical ozone production is studied in acidic solutions or pure water. However, in pure water system, a membrane electrode assembly (MEA) is usually employed. Research on using tap water as the electrolyte for electrochemical ozone production has received insufficient attention. In this study, a nickel/antimony doped tin oxide catalyst electrode was used for ozone production via electrolysis of tap water without membrane. The maximum ozone current efficiency (4.11%) was achieved at a voltage of 7 V, a water pumping rate of 12 mL/min and temperature of 6 °C. These results demonstrate the feasibility of using a nickel/antimony-doped tin oxide catalyst electrode to produce ozonated tap water, and this study provides support for the practical applications of ozonated tap water.
