Removal of carbon monoxide by low temperature plasma-catalysis

Summary form only given. Dielectric barrier discharge as a part of non-thermal plasmas has been widely studied for various applications, such as surface treatment, synthesis of inorganic materials, abatement of pollutants, and hydrocarbon reforming. These applications employ highly reactive species generated in non-thermal plasmas that are favorable to induce physical and chemical reactions at relatively low temperatures¹. In particular, the application of plasma-catalysis hybrid technology for post-process treatment of pollutants has attracted considerable interest because the combination of a plasma with catalysis has a possibility for reducing the operational temperature and cost. For the removal of carbon monoxide at low temperature, the oxidation of carbon monoxide on a catalyst based on platinum was investigated with introducing ozone generated by dielectric barrier discharge. From the experiments, it is found that the carbon monoxide can be dramatically decreased with supplying ozone.
