Promoting ozone synthesis from oxygen by a high performance volume-surface hybrid discharge

A high performance hybrid discharge reactor with a flat-plate configuration, in which volume and surface discharges can occur simultaneously, is designed to achieve a high ozone energy yield at high concentrations. Compared with the single volume/surface dielectric barrier discharge, this hybrid discharge acquires much higher discharge voltage, number density of current pulses, and thus discharge power at the same input power. The optical emission spectroscopy diagnosis indicates that the designed reactor possesses a relatively high electron density, excitation temperature, and low rotational temperature, which facilitates the production of ozone. The excellent performance of the hybrid discharge in ozone production from oxygen demonstrates its high energy efficiency and reliability for the practical application of the ozone synthesis.A high performance hybrid discharge reactor with a flat-plate configuration, in which volume and surface discharges can occur simultaneously, is designed to achieve a high ozone energy yield at high concentrations.
