Understanding the NH3-SCO mechanism over Ag-FAU zeolites combining INS and solid state NMR
Nitric oxides are among the main atmospheric pollutants emitted by stationary power plants and automotive sources. Nowadays, the NH3-SCR is the main technology for the NOx abatement of the exhaust gases in vehicles using a urea tank as a precursor of the NH3 as reducing agent. The use of the NH3-SCR technology leads to NH3 emissions to the atmosphere, which has to be controlled due to the harmful effects on human health and environment. One of the most promising alternatives to combat the NH3 emissions is the Selective Catalytic Oxidation of NH3 (NH3-SCO) in water and N2. The most promising materials for this reaction are the metal-supported catalysts especially containing silver once they show an excellent catalytic behavior. To date, a few works have been published regarding the use of Ag-Zeolites showing that the activation atmosphere of the catalyst, the presence of alkali cations or BrØnsted acid sites affects the catalytic behavior of the silver-based material. In this proposal, we aim to study the interaction of the reactants (NH3+O2) in two different Ag-FAU zeolites: AgNaY (Si/Al ¿ 2.5, Ag/Al = 0.3 and Na/Al = 0.7).
