Mechanism of the reaction of NO and NH3 on vanadium oxide catalyst in the presence of oxygen under the dilute gas condition

The activity and characterization of CeO2-TiO2 catalysts prepared by the sol–gel method for selective catalytic reduction of NO with NH3

“…From the XRD results, N 2 O formation seemed to occur especially on well-ordered cerium oxide crystalline planes. A similar conclusion has been drawn for crystalline chromia [26], crystalline manganese oxide [27], and crystalline [28] and polymeric vanadia species [29].…”

Deactivation of the Vanadia Catalyst in the Selective Catalytic Reduction Process

“…(The NH 3 first chemisorbs on the Bronsted acid site, followed by the bonding of NO on the chemisorbed NH 3 and subsequent decomposition of the complex to N2 and H2O. 6 ) It may be concluded that the dopants which enhance the Bronsted acidity are promoters whereas those weakens it are poisons.…”

Catalysis for NOx abatement

“…Takagi et al proposed one of the first reaction schemes for SCR over V 2 O 5 -based catalysts [137]. Subsequently, Inomata and his group proposed a popular reaction mechanism [138][139][140] in which the reaction of NH þ 4 species occurs with gaseous NO through an 'activated complex' (Fig. 5).…”
