Capillary microplasmas for ozone generation

Microplasmas inside confined cavities, pores and capillaries of dielectric materials present a great potential for various environmental applications. The paper briefly introduces the physical properties of the AC microplasmas generated by the discharges inside porous ceramics foams and focuses on their chemical effects in various mixtures of nitrogen and oxygen. Ozone formation as an example tool to evaluate the chemical potential of the microplasmas was investigated as a function of discharge power, gas mixture composition and total gas flow rate
