"Ab initio" synthesis of zeolites for preestablished catalytic reactions

Gallego-Sánchez, Eva María; Portilla Ovejero, Mª Teresa; Paris-Carrizo, Cecilia Gertrudis; Leon Escamilla, Efigenio Alejandro; Boronat Zaragoza, Mercedes; Moliner Marin, Manuel; Corma Canós, Avelino (American Association for the Advancement of Science (AAAS), 2017)

[EN] Unlike homogeneous catalysts that are often designed for particular reactions, zeolites are heterogeneous catalysts that are explored and optimized in a heuristic fashion. We present a methodol. for synthesizing ...
Conceptual similarities between zeolites and artificial enzymes

Gallego-Sánchez, Eva María; Paris, Cecilia; Cantin Sanz, Angel; Moliner Marin, Manuel; Corma Canós, Avelino (The Royal Society of Chemistry, 2019-09-14)

[EN] By using a Diels-Alder (DA) reaction as a base case, we show that a pure silica zeolite acting as an entropy-trapping scaffold can be synthesized with an organic structure directing agent (OSDA) analogue of the ...
Deactivation and regeneration studies on Pd-containing medium pore zeolites as passive NOx adsorbers (PNAs) in cold-start applications

Bello-Jurado, Estefanía; Margarit Benavent, Vicente Juan; Gallego-Sánchez, Eva María; Schuetze, Frank; Hengst, Christoph; Corma Canós, Avelino; Moliner Marin, Manuel (Elsevier, 2020-08-01)

[EN] Two Pd-containing medium pore zeolite frameworks, MFI and MWW, have been evaluated as passive NOx adsorbers (PNAs) in automotive applications. The NOx adsorption/desorption behavior of Pd-containing standard ZSM-5 and ...
Making Nanosized CHA Zeolites with Controlled Al Distribution for Optimizing Methanol-to-Olefin Performance

Gallego-Sánchez, Eva María; Li, Chengeng; Paris, Cecilia; Martín-García, Nuria; Martínez-Triguero, Joaquín; Boronat Zaragoza, Mercedes; Moliner Marin, Manuel; Corma Canós, Avelino (John Wiley & Sons, 2018-10-01)

[EN] From theoretical calculations and a rational synthesis methodology, it has been possible to prepare nanocrystalline (60-80 nm) chabazite with an optimized framework Al distribution that has a positive impact on its ...
Nanosized MCM-22 zeolite using simple non-surfactant organic growth modifiers: synthesis and catalytic applications

Gallego-Sánchez, Eva María; Paris, Cecilia; Martínez, Cristina; Moliner Marin, Manuel; Corma Canós, Avelino (The Royal Society of Chemistry, 2018-09-14)

[EN] Non surfactant cyclic alkylammonium can selectively decrease the rate of crystal growth along the x-y crystal axes during the synthesis of MWW zeolite. This results in an similar to 60 nm nanocrystalline zeolite that ...
Production of aromatics from biomass by computer-aided selection of the zeolite catalyst

Margarit Benavent, Vicente Juan; Gallego, Eva M.; Paris, Cecilia; Boronat Zaragoza, Mercedes; Moliner Marin, Manuel; Corma Canós, Avelino (The Royal Society of Chemistry, 2020-08-07)

[EN] Taking into account that the transformation of biomass-derived 2,5-dimethylfuran (DMF) top-xylene involves Diels-Alder (DA) cycloaddition as the limiting step, the use of an ITQ-2 zeolite obtained by direct synthesis ...
Simple organic structure directing agents for synthesizing nanocrystalline zeolites

Gallego-Sánchez, Eva María; Paris-Carrizo, Cecilia Gertrudis; Díaz-Rey, Maria Del Rocio; Martínez Armero, Marta Evelia; Martínez-Triguero, Joaquín; Martínez, Cristina; Moliner Marin, Manuel; Corma Canós, Avelino (The Royal Society of Chemistry, 2017)

[EN] The synthesis of the ZSM-5 and beta zeolites in their nanosized form has been achieved by using simple alkyl-substituted mono-cationic cyclic ammonium cations as OSDA molecules. The particular combination of a cyclic ...
SÍNTESIS DE ZEOLITAS CON PROPIEDADES TEXTURALES Y DE CONFINAMIENTO ADECUADAS PARA SU USO COMO CATALIZADORES EN REACCIONES QUÍMICAS DE INTERÉS INDUSTRIAL

Gallego Sánchez, Eva María (Universitat Politècnica de València, 2020-01-07)

[ES] Las zeolitas son materiales microporosos cristalinos formados por una red de tetraedros TO4 (T = Si, Al, Ti, ...) interconectados entre sí compartiendo átomos de oxígeno, que generan estructuras tridimensionales ...
