SGER: Non-thermal Plasma Reactors with Reticulated Vitreous Carbon Electrodes Coated with Catalysts

气相脉冲电晕反应器已被用于降解和去除空气污染物，如燃烧气体和其他气态废物流中的氮氧化物、二氧化硫和挥发性有机化合物。脉冲流光电晕放电产生的流光通道从一个电极传播到另一个电极，通常具有相对较小的直径。这些飘带导致形成化学反应降解转化为危害较小的副产品的许多污染物。PI正在研究网状玻璃体碳作为脉冲电晕反应器的高压和接地电极。在这种应用中使用网状玻璃碳电极的主要优点是，它允许气体流过等离子体强度最高的电极区域，从而促进气体中废物组分与等离子体区域之间的良好接触。此外，初步工作表明二氧化氮与电极表面之间可能存在相互作用。本项目旨在探索通过在网状碳电极上涂覆铂等材料，以促进还原反应，从而改善反应器除氮操作的可能性。

AbstractBruce Locke and Ronald ClarkeFlorida State University0071351Gas phase pulsed corona reactors have been used for the degradation and removal of air pollutants such as nitrogen oxides, sulfur dioxide and volatile organic compounds from combustion gases and other gaseous waste streams. A pulsed streamer corona discharge creates streamer channels that propagate from one electrode to the other and that typically have relatively small diameter. These streamers lead to the formation of chemically reactive degradation of conversion to less harmful byproducts of many pollutants.The PI's are working on reticulated vitreous carbon as high voltage and ground electrodes in pulsed corona reactors. The major advantage of using reticulated vitreous carbon electrodes for this application is that it allows for the gas to flow through the electrode region where the plasma has the highest intensity, thereby facilitating good contact between the waste components in the gas and the plasma region. In addition, preliminary work has indicated possible interactions between nitrogen dioxide and the surface of the electrodes. This project is to explore the possibility of improving the reactor operation for nitrogen oxide removal through the coating of the reticulated carbon electrodes with platinum and other materials in order to promote reductive reactions.
