“…Catalytic test reproducibility was performed by repeating the same light-off test (control test) regularly as shown elsewhere [9]. NO conversion exhibits a constant standard deviation around 1.5% in the whole range of temperature.…”

“…In a previous work [9] we demonstrated the good catalytic performance of VO x /TiO 2 catalyst in the simultaneous removal of NO and o-dichlorobenzene (o-DCB, a model molecule to simulate PCDD/Fs), although it is rather complex system, since chemical composition of the molecules is completely different and the abatement reactions (Eq. 1-2) follow different reaction mechanism, not necessarily independent.…”

“…Moreover, the competitive mechanism between NO reduction and o-DCB oxidation reactions for acid and redox sites, leads to reduce the conversion of both pollutants at high temperature (> 300 °C) [9,10]. Nonetheless, the NO 2 formed by NO oxidation reaction enhances the o DCB conversion at low temperature (< 300 °C) [9][10][11][12]. Then, we concluded that the challenge of dDiNOx process is to broaden the operating temperature window, (the temperature range at which the conversion of both pollutants is higher than 60%) both by adjusting operating conditions and by improving catalyst composition.…”

MnOX-CeO2 catalysts with different Mn and Ce content were prepared to evaluate the effect of metal content on catalytic properties and activity in the simultaneous NO reduction and o-DCB oxidation, in order to elucidate the most active species for the process. Catalytic properties were evaluated by ICP-AES, XRD, skeletal FTIR, STEM-HAADF, XPS, N2-physisorption, H2-TPR, NH3-TPD and pyridine-FTIR. Catalysts with 85%Mn and 15%Ce molar content have been found to be the most active. Their excellent catalytic performance is related to the coexistence of Mn in different phases, i.e., Mn species strongly interacting with Ce and segregated Mn species. The effect of the preparation methods has also been deeply investigated: Co-precipitation method (CP) leads to Mn segregation as Mn2O3, whereas sol-gel preparation method (SG) promotes the formation of an amorphous powder. The synergy between segregated Mn2O3 species and Mn species in high interaction with Ce (resulting in a mixed oxide phase) leads to the presence of Mn with different oxidation states. This effect, together with the high oxygen mobility caused by structural defects, enhances redox, acidic and oxidative properties. The improvement of catalytic properties with Mn content also favors NO reduction side-reactions, with N2O and NO2 being the most important by-products, whereas it limits the production of chlorinated organic by-products in o-DCB oxidation.
