Ozone synthesis from oxygen in dielectric barrier discharges

TLDR

The study presents a comprehensive model of ozone generation in dielectric barrier discharges. The model integrates micro‑discharge physics with ozone chemistry through an extensive reaction scheme of electronic and ionic processes. The model shows that excited atomic and molecular states are critical, establishes theoretical limits on production efficiency and concentration, identifies key performance parameters, and agrees with experimental data.

Abstract

A comprehensive model of ozone generation in dielectric barrier discharges is presented. The model combines the physical processes in the micro-discharges with the chemistry of ozone formation. It is based on an extensive reaction scheme including the major electronic and ionic processes. The importance of excited atomic and molecular states is demonstrated. Theoretical limits are given for the ozone production efficiency and the attainable ozone concentration. The most important parameters influencing the performance of ozonisers are identified. All theoretical predictions are compared to measured data.
