The combination of a nonthermal plasma and a heterogeneous catalyst provides unique opportunities for chemical transformations. High densities of reactive species, such as ions, radicals or vibrationally excited molecules, are generated by electron collisions and initiate a multitude of chemical reactions in the gas phase. By shifting the reaction site from the gas phase to the surface of the catalyst, the selectivity of these reactions can be significantly enhanced. Dielectric barrier discharges (DBDs) are a promising plasma source for these kinds of applications due to their non‐equilibrium conditions and their simple construction. This review provides a brief introduction to the breakdown mechanism and the various geometries of DBDs and presents several plasma‐catalytic DBD applications.

大气压下等离子体催化过程中介电势垒放电的基本特性和应用

非热等离子体和非均相催化剂的结合为化学转化提供了独特的机会。电子碰撞产生高密度的反应性物质，例如离子，自由基或振动激发的分子，并在气相中引发多种化学反应。通过将反应部位从气相转移到催化剂表面，可以显着提高这些反应的选择性。介电势垒放电（DBD）由于其非平衡条件且结构简单，因此是用于此类应用的有希望的等离子体源。这篇综述简要介绍了DBD的分解机理和各种几何形状，并介绍了几种等离子体催化DBD应用。
