Study on electrosynthesis of ozone in the low-temperature plasma medium

Abstract

This article analyzes the state of the art of ozone electrosynthesis, reveals the shortcomings of existing methods of ozone electrosynthesis, and identifies research directions. A theoretical analysis of ozone electrosynthesis processes using sinusoidal voltages and periodic acute-angled voltage pulses with an amplitude factor of more than 5 is carried out. The calculation of the electric intensity values in the elements of the ozone generator when powered by sinusoidal and impulse voltage is highlighted. Experimental studies have confirmed the results of theoretical studies and revealed the reasons for the heating of the dielectric barrier with sinusoidal power supply. It was found that when powered by a pulsed voltage, due to a significant increase in the amplitude value of the electric field strength, the conductivity of the discharge gap increases sharply with the formation of low-temperature plasma and intense ultraviolet radiation, which leads to a sharp increase in the energy parameters of the ozone electrosynthesis process and the absence of the dielectric barrier heating process.
