“…Among these catalysts, V 2 O 5 /TiO 2 in combination with MoO 3 and WO 3 has been commercialized in consequence of its high catalytic reactivity, including NO conversion, N 2 selectivity and resistance to sulfur poisoning, and mechanical strength. In view of high reaction temperature and environmental toxicity of vanadium species (Liu and He, 2010;Liu et al, 2011b;Ma et al, 2011;Youn et al, 2016), vanadium-free catalysts attracted much attention including M-zeolite catalysts (M-Fe, Cu, Mn, Mo) (Pérez-RamıŔez et al, 2004;Yoshida et al, 2004;Liu et al, 2011a;Ochońska et al, 2012;Schuricht and Reschetilowski, 2012;Mejri et al, 2016) and metal oxides catalysts (Fe, Mn, Cu, Ce, Cr, etc. ) (Kato et al, 1981;Baksh et al, 1992;Kapteijn et al, 1994;Chen et al, 1995;Schneider et al, 1995;Zhu et al, 1999;Eigenmann et al, 2006;Min et al, 2007;Xu et al, 2008;Liu et al, 2013a;Shin et al, 2016).…”

“…This provides au nique environment for isolated catalytically active centers such as metal and metal-oxo species. Transition-metal-exchanged zeolites, for instance, find increasedapplication in selective catalytic reduction of NO x [15][16][17][18][19][20][21][22][23][24][25] and show potentiali no xidation reactions such as methane activation. [7][8][9][10][11][12][13][14] Generally,t wo different pathways exist for the exchange of transition-metalc ations in zeolite frameworks (Scheme 1a nd Supporting Information, Figure S1).…”

“…The study coverst hree different oxidation states, that is, metals include Co, [26][27][28][29] Fe, [7,18,[30][31][32][33] Ni, [34][35][36] Pd, [37] Pt, [38] and Ag. [24,39] Framework exchange of transition metalsi nz eolites has also received great attention.F or example iron, [40][41][42][43][44][45] cobalt, [46] vanadium, [47] and titanium-exchanged zeolites have been synthesized and characterized. Owing to the growingi mportanceo ft ransition-metal-exchanged zeolites, al arge number of theoretical studies concerning transition-metal-exchanged zeoliteshave appeared.…”

“…It would be favorable to reduce both the pollutants in one catalytic bed, using the same reducing agent as natural gas. Thus far, few papers were addressed to simultaneous selective catalytic reduction with hydrocarbons in a double catalytic bed [4][5][6][7], or in a single catalytic bed [8,9]. When a single catalyst was adopted for the simultaneous abatement, it was suggested that the nitrogen oxides partially competed for the same active sites [9].…”
