Advances and perspectives from a decade of collaborative efforts on zeolites for selective catalytic reduction of NOx

Vennestrøm, Peter N.R.; Thogersen, Joakim R.; Gabrielsson, Pär L. T.; van Tendeloo, Leen; Schütze, Frank W.; Moliner Marin, Manuel (Elsevier, 2022-12)

[EN] Nitrogen oxides (NOx) is a major air pollutant and its release is regulated by increasingly stringent legislation. Selective catalytic reduction using ammonia as a reductant (NH3-SCR) is the most widely applied method ...
Cage-based small-pore catalysts for NH3-SCR prepared by combining bulky organic structure directing agents with modified zeolites as reagents

Martín-García, Nuria; Paris, Cecilia; Vennestrom; Peter Nicolai Ravnborg; Thogersen, Joakim Reimer; Corma Canós, Avelino; Moliner Marin, Manuel (Elsevier, 2017)

[EN] It has been possible to efficiently synthesize high-silica ERI and AFX zeolites with nano-sized primary crystallites (30-200 nm). This was achieved by using a dicationic and rigid organic structure directing agent ...
Design, synthesis and characterization of small-pore zeolites for industrial environmental applications

Boruntea, Cristian-Renato (Universitat Politècnica de València, 2020-04-21)

[ES] El Proyecto de investigación aquí descrito se estructura en dos partes. La primera parte se centra en la investigación fundamental con el objetivo de crear un protocolo para la síntesis de zeolitas. La segunda parte ...
Improving the catalytic performance of SAPO-18 for the methanol-to-olefins (MTO) reaction by controlling the Si distribution and crystal size

Martínez Franco, Raquel; Li, Zhibin; Martínez Triguero, Luis Joaquín; Moliner Marin, Manuel; Corma Canós, Avelino (Royal Society of Chemistry, 2016)

[EN] The physico-chemical properties of the small pore SAPO-18 zeotype have been controlled by properly selecting the organic molecules acting as organic structure directing agents (OSDAs). The two organic molecules selected ...
One-Pot Synthesis of CHA/ERI-Type Zeolite Intergrowth from a Single Multiselective Organic Structure-Directing Agent

Kwon, Soonhyoung; Bello-Jurado, Estefanía; Ikonnikova, Evgeniia; Lee, Hwajun; Schwalbe-Koda, Daniel; Corma Canós, Avelino; Willhammar, Tom; Olivetti, Elsa A.; Gomez-Bombarelli, Rafael; Moliner Marin, Manuel; Román-Leshkov, Yuriy (American Chemical Society, 2024-03-13)

[EN] We report the one-pot synthesis of a chabazite (CHA)/erionite (ERI)-type zeolite intergrowth structure characterized by adjustable extents of intergrowth enrichment and Si/Al molar ratios. This method utilizes readily ...
Reversible Transformation of Pt Nanoparticles into Single Atoms inside High-Silica Chabazite Zeolite

Moliner Marin, Manuel; Gabay, Jadeene E.; Kliewer, Chris E.; Carr, Robert T.; Guzman, Javier; Casty, Gary L.; Serna Merino, Pedro Manuel; Corma Canós, Avelino (American Chemical Society, 2016-12-07)

[EN] We report the encapsulation of platinum species in highly siliceous chabazite (CHA) crystallized in the presence of N,N,N-trimethyl-1-adamantammonium and a thiol-stabilized Pt complex. When compared to Pt/SiO2 or ...
