“…This behavior is in agreement with various published studies such as that of Harling et al [32] who showed, in the case of toluene and cyclohexane, that ozone cannot directly decompose the pollutants. Ozone dissociates into oxygen radicals, via its adsorption on the catalyst, which then takes part in the catalytic reaction [60].…”

“…It is also worthy to mention that plasma-catalytic reactions improved by ozone were vastly investigated. More specifically, the VOCs abatement on MnO 2 and CeO 2 oxides supported on a large panel of materials (Al 2 O 3 , TiO 2 , zeolites) have been studied [27][28][29][30][31][32].…”

“…The by-product analysis indicates that TCE is only partially mineralized. This demonstrates one of the shortcomings of NTP which can be improved by catalyst hybridization [14][15][16]. Figure 3 shows the effect of the initial TCE concentration on the RE for both negative and positive corona.…”

The decomposition of trichloroethylene (TCE) in air by non-thermal plasma was investigated with a multi-pin-to-plate direct current (DC) discharge at atmospheric pressure and room temperature. The effects of various operating parameters on the removal efficiency (RE) were examined. The experiments indicated that for low energy densities higher removal could be obtained with positive corona. For negative corona and 10% relative humidity (RH) a maximum RE of 99.5% could be achieved at 1100 J L -1 . Formation of byproducts was qualitatively analyzed in detail with FT-IR spectroscopy and mass spectrometry. Detected by-products for negative corona operated at 300 J L -1 and 10% RH include dichloroacetylchloride, trichloroacetaldehyde, phosgene, ozone, HCl, Cl 2 , CO and CO 2 . The highest RE for TCE was achieved with a relative humidity of 19%.

“…During the present study, at 230 J/l, 350 ppm of ozone was observed, whereas at the same input energy MnO 2 and TiO 2 /MnO x /SMF showed complete destruction of ozone. Decomposition of ozone on MnOx may lead to the formation of atomic oxygen that may improve the performance of the NTP reactor (Futamura and Gurusamy 2005;Harling et al 2009;Karuppiah et al 2010). However, TiO 2 may not show any appreciable activity for ozone decomposition.…”

Oxidative decomposition of dilute benzene in air was carried out in a dielectric barrier discharge reactor with inner metal fiber electrode that was later modified with transition metal oxides. Typical results indicated the best performance of the designed reactor for the removal of dilute benzene, where conventional techniques may not be efficient. The introduction of transition metal oxides in the discharge zone increased the conversion of benzene and shifted the product distribution to total oxidation. The performance of the reactor was further improved on humidification of air stream. The better performance of MnO x /SMF over CoO x and SMF may be due to in situ decomposition of ozone that may lead to the formation of strong oxidant atomic oxygen, whereas the best performance with TiO 2 /MnO x /SMF may be assigned due to the synergy between ozone decomposition on MnO x surface and photocatalytic action on TiO 2 .
