“…The advantage of the microplasmas is that they produce high densities of chemically active species at relatively low energy consumption without any vacuum equipment requirements. The atmospheric microplasmas can be generated by various types of electric discharges, including hollow cathode and capillary plasma electrode discharges [1][2][3][4][5], discharges in porous ceramics and capillary honeycombs [6][7][8][9][10] or dielectric barrier and coplanar discharges [11][12][13].…”

Abstract. 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.

“…There are a small number of previous publications on DBD plasma assisted electrolysis. Whilst the electrolyte of the devices used varies from proton exchange membrane (Nafion) (9, 10), proton conducting solid electrolytes (BCY) (11), to more typical solid oxide materials (YSZ) (12,13), the focus of these publications was the use of plasma to assist in catalysis to improve conversion rates.…”

This work focuses on the development of a bespoke rig which allows for the simultaneous use of non-thermal plasmas (NTPs), oscillating gas flow via a Desai-Zimmerman Fluidic Oscillator (DZFO) and a Solid Oxide Cell (SOC) to create a highly efficient energy conversion device to facilitate the reduction of CO 2 to CO. Both fluidic oscillation and NTPs have the potential to reduce resistances in a SOC, key to furthering their commercialisation. The potential role of NTPs in improving the kinetics and efficiency of reactions relevant to CO 2 reduction, such as the dissociation of CO 2 , is presented. Performance improvements using a rapidly oscillating gas flow, provided by the DZFO, to minimise concentration polarisation resistance by disrupting boundary layer formation and increasing overall efficiency are also discussed. The intersection of these technologies provide a path for a paradigm shift in the ability to convert waste CO 2 into high value feedstock using renewable energy.

“…Multi-species conduction broadens both the realm of potential applications and also the potential challenges for the technical use of these perovskite materials. Applications that could harness these multi-species conduction effects include sensors, hydrogen and oxygen separation membranes, 2,3 membrane reactors, 2,4 and the chemical permeation of steam. 5 At the same time, however, multi-species ionic transport can also introduce limitations to the use of these perovskite materials as electrolytes in high-drain electrochemical devices such as fuel cells, [6][7][8] an area where they are currently seeing significant application.…”
