Selective catalytic reduction of nitric oxide by ammonia over Cu-exchanged Cuban natural zeolites

Incorporation of Copper in SiBEA Zeolite as Isolated Lattice Mononuclear Cu(II) Species and its Role in Selective Catalytic Reduction of NO by Ethanol

“…8) shows a volcano-shape behavior, typical of various catalytic systems (Cuexchanged natural zeolite [24], Co-exchanged MFI [25], CoSiBEA [26] and FeSiBEA [27]) and reveals the transition from a kinetic regime (presence of organic molecules in the reaction zone) to a thermodynamic one (NO/NO 2 equilibrium, when organic molecules are exhausted).…”

“…Also, they have a quite large application range: agriculture (Colella, 1999(Colella, , 2007Li, 2003;Reh akova et al, 2004;Spedding, 1984), medicine (Bonferoni et al, 2007;Cerri et al, 2004;Colarte, 2006;Grce and Paveli c, 2005;Izmirova et al, 2001;Poljak Blazi et al, 2001), separaration of gases (Ackley et al, 1992(Ackley et al, , 2003Jayaraman et al, 2004), catalysis (Cobzaru et al, 2008;Mishima et al, 1998;Moreno-Tost et al, 2004;Onyesty ak et al, 2004;St€ ocker, 2005;Yilmaz et al, 2005), etc. But the most applications of the native zeolites are directed to the treatments of drinking and wastewaters (Argun, 2008;Arma gan, 2003;Doula, 2006;Doula and Dimirkou, 2008;Elizalde-Gonzalez et al, 2001;Elizondo et al, 2000;Erdem et al, 2004;Faghihian et al, 1999;Hodi et al, 1995;Hung and Lin, 2006;Langella et al, 2000;Zamzow et al, 1990;Zrncevic and Gomzi, 2005).…”
