Abstract :
Cooperative effect of catalysts with nonthermal plasma processing for dilute (100 ppm or 1000 ppm) TCE decomposition in air was investigated. As catalysts, titania, TiO2, was tested. One sample was 2-3 mm sphere pellets coated with vanadium oxide, V2 O5. Hand-made titania pellets with various sizes were also tested. GCMS analysis suggested that the catalyst assisted to decompose TCE with small energy but generated some byproducts. The results suggested the size and surface states of catalyst particulates were very important to determine discharge mode and energy efficiency was strongly dependent on the discharge mode
