“…Catalytic oxidation represents the current state of the art technique used commercially for the destruction for PCDD/PCDFs. In particular, V 2 O 5 /TiO 2 -based catalysts, employed in most incinerators for the control of NO x emissions via the selective catalytic reduction with NH 3 , are also active for the oxidation of PCDD/PCDFs [3][4][5][6][7]. In addition to PCDD/PCDFs and NO x , incinerator flue gas streams also contain complex mixtures of both halogenated and non-halogenated volatile organic compounds (i.e., biphenyls and polyaromatic hydrocarbons [8]).…”

“…This issue has been raised by the study on O-VOC because it revealed that some of the strategies proposed to optimize the formulations would only be beneficial for (chloro)-aromatics but would not apply to entire dioxin applications. These results should definitively encourage researchers to integrate fundamental approaches with model VOC with the results of real plant investigations [44,58,[86][87][88][89][90]. Laboratory research on entire dioxins [91] should also bring precious insights on the issue but this, for sure, should be carried out in highly safe facilities.…”

For several years, the authors study VO x /TiO 2 catalytic formulations in the context of the oxidative abatement of aromatics, possibly chlorinated, from polluted air. This paper revisits their main findings and understandings. Although VO x /TiO 2 catalysts, when upgraded with Mo or W oxides, are already used in industrial applications, it is shown that the systematic investigation (i) of the reasons why optimized synthesis and formulations are indeed efficient, (ii) of the nature of the sites responsible for the adsorption of the pollutants and their catalytic transformation, and (iii) of the corresponding mechanisms, is a valuable approach to identify guidelines and strategies for further improving the catalysts. The origin of the beneficial effects brought by WO x and MoO x to VO x /TiO 2 , and by the use of a sulphated titania support, is addressed, as well as the impact on the catalysts behaviour and performances of molecules inevitably present in a combustion exhaust gas, like CO and NO x co-pollutants and water. The behaviours of a chloroaromatic molecule, like chlorobenzene, and an oxygen containing-heterocyclic molecule, like furan and dimethylfuran, are then compared and discussed in the debate of their selection as representative model compounds for the catalytic abatement of dioxins. In this context, it is shown that strategies developed to improve the performances of VO x /TiO 2 formulations to abate Cl-aromatics, could be detrimental for cyclic molecules containing O-heteroatom, as entire dioxins. Finally, an integrated view of the catalytic process is presented by envisaging the case of a complex mixture, closer to the real application of gaseous effluent cleaning.

“…Previous studies revealed that NH 3 -SCR catalysts (V 2 O 5 -WO 3 /TiO 2 ) could effectively promote the decomposition of PCDD/Fs through catalytic oxidation reactions (Boos et al, 1992;Dvorák et al, 2010;Jones and Ross, 1997). In Europe and Japan, commercial V 2 O 5 -WO 3 /TiO 2 catalysts have been applied in MSWIs to remove PCDD/Fs and NO x simultaneously (Bonte et al, 2002;Ide et al, 1996). In comparison to the NH 3 -SCR catalysts only designed for NO x removal, higher vanadium contents are commonly needed to increase the oxidation potential of the catalysts (Debecker et al, 2011;Weber et al, 1999;Yang et al, 2008).…”
