“…Vandenbroucke et al [13] reviewed the present understanding of the mechanisms involved in plasma catalysis process and studied the decomposition of toluene with plasma catalysis on laboratory scale [14]. In the research by Futamura et al [15], a silent discharge plasma reactor has been hybridized with different catalysts (MnO 2 , TiO 2 and TiO 2 -silica gel) for benzene decomposition. They described the mechanism for MnO 2 -catalyzed oxidation of benzene ( Figure 4).…”

The applications of nano-surface chemistry in the field of spectral analysis have attracted growing interest in recent years. In this article, we reviewed the applications of nanomaterials-based chemical reactions for spectral analysis, including the development in plasma-catalysis, surface-enhanced spectroscopy, separation and preconcentration, chemical vapor generation, labeling and signal amplification. Introduction of nano-surface chemistry to spectral analysis not only improves the sensitivity and selectivity, broadens the application range of spectral analysis, but also affords analytical community special characterization tools.surface chemistry, nanomaterial, plasma, separation, chemical vapor generation, opticle gas sensors, atomic spectrometry Citation:Li C H, Liu R, Lü Y, et al.

“…compare to the conventional technologies (Magureanu et al, 2005;Zhu et al, 2008b). In the field of air pollution control, the NTP tech nology h as been tested for the abatement of var ious types of hazardous air pollutants such as volatile organic compounds (VOCs) (Ogata et al, 1999;Urashima and Chang, 2000;Futamura et al, 2004;Magureanu et al, 2007;Subrahmanyam et al, 2007), SO 2 (Mizuno, et al,1986;Changet al,1991), NOx (Ohkubo et al,1994;Tonkyn et al,2003;Young et al, 2004), CFCs (Li and Ma, 2000;Gal et al, 2003;Park et al, 2003;Ricketts et al, 2004) odors (Masuda et al, 1993;Mizuno et al,1993;Chang and Tseng, 1996;Zhu et al, 2007), mercury (Masuda,1988), etc. In order to further improve the energy efficiency of the VOCs removal decomposition process by the plasma, the cooperation with catalyst has been tested by some researchers (Einaga et al, 2001;Guo et al, 2006;Kim, 2006;Kim et al, 2008).…”

Synergistic effect of atmospheric non-thermal plasma generated by dielectric barrier discharge and nano titania photocatalyst for benzene decomposition was tested. The paper indicated the effect of photocatalyst on removal efficiency of benzene, the compare of photocatalyst characteristic in different high temperatures by heat treatment, analysis of by-products. The results showed that the effect of degradation was visible by added photocatalyst in the plasma reactor. When concentration of benzene was 600 mg/m 3 and electric field strength was 10 kV/cm, the removal efficiency of benzene was increased up to 81 % without photocatalyst. At the same condition, the removal efficiency was increased to 15 % higher with photocatalyst. Nano titania crystal was anatase crystal in 450 o C heat treatment which is best for benzene removal. The plasma reactor packed with photocatalyst shows a better selectivity of carbon dioxide than that without photocatalyst. By-products are mostly carbon dioxide, water and a small quantity of carbon monoxide.

“…In this context, non-thermal plasma (NTP) produced at atmospheric pressure could be a method of choice. In NTP, the electrical energy is primarily utilized for the production of energetic electrons, leaving the background gas nearly at room temperature [6][7][8][9][10][11][12][13]. In addition, NTP produces active species like radicals, excited molecules and ions.…”

Catalytic gas-phase abatement of air containing 250 ppm of isopropanol (IPA) was carried out with a novel dielectric barrier discharge (DBD) reactor with the inner catalytic electrode made of sintered metal fibers (SMF). The optimization of the reactor performance was carried out by varying the voltage from 12.5 to 22.5 kV and the frequency in the range 200-275 Hz. The performance was significantly improved by modifying SMF with Mn and Co oxide. Under the experimental conditions used, the MnO x /SMF showed a higher activity towards total oxidation of IPA as compared to CoO x /SMF and SMF electrodes. The complete destruction of 250 ppm of IPA was attained with a specific input energy of~235 J/L using the MnO x /SMF catalytic electrode, whereas, the total oxidation was achieved at 760 J/L. The better performance of the MnO x /SMF compared to other catalytic electrodes suggests the formation of short-lived active species on its surface by the in-situ decomposition of ozone.
