  • Title: Combination of plasma with a honeycomb-structured catalyst for automobile exhaust treatment.
    Author: Kang WS, Lee DH, Lee JO, Hur M, Song YH.
    Journal: Environ Sci Technol; 2013 Oct 01; 47(19):11358-62. PubMed ID: 23991700.
    Abstract:
    To activate a catalyst efficiently at low temperature by plasma for environmental control, we developed a hybrid reactor that combines plasma with a honeycomb-structured catalyst in a practical manner. The reactor developed generated stable cold plasma at atmospheric pressure because of the dielectric and conductive nature of the honeycomb catalyst by consuming low amounts of power. In this reactor, the applied voltage and temperature determined the balance between the oxidation and adsorption by the plasma and catalyst. The synergistic reaction of the plasma and catalyst was more effective at low temperatures, resulting in a reduction in a lowered light-off temperature.
