Modulating the Electron Temperature of Spark Discharge for Highly Efficient Production of HNO 3

Key Points

• The aim is to investigate how adjusting the electron temperature of spark discharge affects the production efficiency of nitric acid (HNO3).
• Utilized spark discharge technique to modulate electron temperature.
• Measured HNO3 concentration at various electron temperature settings over a 12-hour period.
• Analyzed solution concentration to determine production efficiency.
• Achieved HNO3 concentration of up to 680.5 mM within 12 hours of discharge time.
