Plasma as the fourth state of matter is an ionized gas consisting of both negative and positive ions, electrons, neutral atoms, radicals, and photons. In the last few decades, atmospheric-pressure plasmas have started to attract increasing attention from both scientists and industry due to a variety of potential applications. Because of increasing interest in the topic, the focus of this book is on providing engineers and scientists with a fundamental understanding of the physical and chemical properties of different atmospheric-pressure plasmas via plasma diagnostic techniques and their applications. The book has been organized into two parts. Part I focuses on the latest achievements in advanced diagnostics of different atmospheric-pressure plasmas. Part II deals with applications of different atmospheric-pressure plasmas.

Non-equilibrium atmospheric pressure plasma jets (APPJs) are of intense interest in current low-temperature plasma research because of their immense potential for material processing and biomedical applications. Depending on the jet configuration and the electrical excitation, plasma characteristics including heat, charged particle, electric field, and chemically active species may differ significantly. Other important parameters of importance in these studies are the kind of utilized working gas and gas flow rate. This book presents the electrical characterization of DBD-based APPJs for three electrode arrangements: ring electrode, pin electrode and floating helix electrode configurations. The analysis presented here will serve to help in establishing an optimum range of operation for a cold plasma jet without arcing and without any physical damage to the electrodes. Furthermore, the experimental results provided in the book establish the significance of the type of working gas on the power consumption and on the jet length obtained. These developed cold DBD-based APPJs of larger lengths may be useful for diverse biological applications and surface treatments.

Plasma catalysis is gaining increasing interest for various gas conversion applications, such as CO2 conversion into value-added chemicals and fuels, N2 fixation for the synthesis of NH3 or NOx, methane conversion into higher hydrocarbons or oxygenates. It is also widely used for air pollution control (e.g., VOC remediation). Plasma catalysis allows thermodynamically difficult reactions to proceed at ambient pressure and temperature, due to activation of the gas molecules by energetic electrons created in the plasma. However, plasma is very reactive but not selective, and thus a catalyst is needed to improve the selectivity. In spite of the growing interest in plasma catalysis, the underlying mechanisms of the (possible) synergy between plasma and catalyst are not yet fully understood. Indeed, plasma catalysis is quite complicated, as the plasma will affect the catalyst and vice versa. Moreover, due to the reactive plasma environment, the most suitable catalysts will probably be different from thermal catalysts. More research is needed to better understand the plasma–catalyst interactions, in order to further improve the applications.
