Ammonia-Containing Species Formed in Cu-Chabazite As Per In SituEPR, Solid-State NMR, and DFT Calculations

Moreno González, Marta; Hueso Fuentes, Beatriz; Boronat Zaragoza, Mercedes; Blasco Lanzuela, Teresa; Corma Canós, Avelino (American Chemical Society, 2015-03-19)

Nowadays, the most attractive technology for the elimination of nitric oxides from the exhaust gas of diesel vehicles is the selective catalytic reduction with ammonia (NH3-SCR-NOx) using Cu zeolite with the chabazite ...
APLICACIÓN DE TÉCNICAS ESPECTROSCÓPICAS IN SITU AL ESTUDIO DE REACCIONES DE INTERÉS MEDIOAMBIENTAL: ELIMINACIÓN DE ÓXIDOS DE NITRÓGENO

Moreno González, Marta (Universitat Politècnica de València, 2015-07-02)

[EN] The Selective Catalytic Reduction of nitrogen oxides (SCR-NOx) is nowadays a very relevant process for reducing NOx emissions in diesel vehicles, which must comply with increasingly restrictive European regulations. ...
Caracterización de catalizadores de cobre utilizados en la reacción de reducción catalítica selectiva de óxidos de nitrógeno utilizando técnicas de resonancia magnética

Moreno González, Marta (Universitat Politècnica de València, 2012-05-04)

Se ha llevado a cabo el estudio de tres catalizadores zeolíticos intercambiados con Cu(II): Cu-IM5 (relación molar Si/Al = 12, Cu/Al=0,65), Cu-SSZ-13 (Si/Al=22, Cu/Al=0,46) y Cu-SSZ-13 (Si/Al=11, Cu/Al=0,15), que muestran ...
Evidence of a Cu2+-Alkane Interaction in Cu-Zeolite Catalysts Crucial for the Selective Catalytic Reduction of NO with Hydrocarbons

Moreno González, Marta; Palomares Gimeno, Antonio Eduardo; Chiesa, Mario; Boronat Zaragoza, Mercedes; Giamello, Elio; Blasco Lanzuela, Teresa (American Chemical Society, 2017)

[EN] The selective catalytic reduction of NOx with hydrocarbons (HC-SCR-NOx) on Cu-zeolites is an alternative for the depletion of NOx present in the exhaust gas of diesel engines. The role played by copper and the general ...
Modeling of EPR Parameters for Cu(II): Application to the Selective Reduction of NOx Catalyzed by Cu-Zeolites

Fernández-Villanueva, Estefanía; Moreno González, Marta; Moliner Marin, Manuel; Blasco Lanzuela, Teresa; Boronat Zaragoza, Mercedes; Corma Canós, Avelino (Springer-Verlag, 2018-06)

[EN] We present a combined theoretical-experimental study aiming to provide information about the location and coordination environment of the Cu2+ species involved in the selective reduction of NOx with NH3 catalyzed by ...
Spectroscopic Evidence and Density Functional Theory (DFT) Analysis of Low-Temperature Oxidation of Cu+ to Cu2+NOx in Cu-CHA Catalysts: Implications for the SCR-NOx Reaction Mechanism

Moreno-González, Marta; Millán-Cabrera, Reisel; Concepción Heydorn, Patricia; Blasco Lanzuela, Teresa; Boronat Zaragoza, Mercedes (American Chemical Society, 2019-04-05)

[EN] Despite the intense investigation on the NH3-SCR-NOx reaction mechanism catalyzed by small pore Cu-CHA zeolites, neither the rate-determining step of the process nor the exact nature of the active sites under reaction ...
Study of propane oxidation on Cu-zeolite catalysts by in-situ EPR and IR spectroscopies

Moreno González, Marta; Blasco Lanzuela, Teresa; Góra-Marek, Kinga; Palomares Gimeno, Antonio Eduardo; Corma Canós, Avelino (Elsevier, 2014-05-15)

Three Cu-zeolites with different structure, Cu-TNU-9, Cu-ITQ-2 and Cu Y have been tested as catalysts for propane oxidation reaction. The activity follows the trend: Cu-TNU-9 > Cu-ITQ-2 > Cu Y, and in situ electron ...
