A Lamellar MWW Zeolite With Silicon and Niobium Oxide Pillars: A Catalyst for the Oxidation of Volatile Organic Compounds

Schwanke, Anderson Joel; Balzer, Rosana; Lopes, Christian Wittee; Meira, Debora Motta; DÍAZ MORALES, URBANO MANUEL; Corma Canós, Avelino; Pergher, Sibele (John Wiley & Sons, 2020-08-17)

[EN] In this work, an MWW-type zeolite with pillars containing silicon and niobium oxide was synthesized to obtain a hierarchical zeolite. The effect of niobium insertion in the pillaring process was determined by combining ...
Dandelion-Like Microspherical MCM-22 Zeolite Using BP 2000 as a Hard Template

Schwanke, Anderson; Villarroel-Rocha, Jhonny; Sapag, Karim; DÍAZ MORALES, URBANO MANUEL; Corma Canós, Avelino; Pergher, Sibele (American Chemical Society, 2018-06)

[EN] The chemistry between layered MWW zeolite and carbon black pearls (BP 2000) as an inexpensive hard template was investigated to develop a rational one-pot synthesis of MCM-22 microspheres. The characterization results ...
Recyclable swelling solutions for friendly preparation of pillared MWW-type zeolites

Schwanke, Anderson Joel; Díaz Morales, Urbano Manuel; Corma Canós, Avelino; Pergher, Sibele (Elsevier, 2017)

[EN] We studied the recycling of swelling solution of MWW-type lamellar zeolitic precursor with a Si/Al = 25. Swollen materials were obtained up to a third reuse without any compensation of reactants, pH or decrease of ...
The influence of ethanol-assisted washes to obtain swollen and pillared MWW-type zeolite with high degree ordering of lamellar structure

Schwanke, Anderson Joel; DÍAZ MORALES, URBANO MANUEL; Corma Canós, Avelino; Pergher, Sibele (Elsevier, 2019-02)

[EN] We studied the influence of the ethanol used as a washing solvent for obtaining swollen and pillared MWW topology zeolites with long-range ordering of lamellar structure. The diffractogram results showed that the ...
The influence of swelling agents molecular dimensions on lamellar morphology of MWW-type zeolites active for fructose conversion

Schwanke, Anderson Joel; Pergher, Sibele; Díaz Morales, Urbano Manuel; Corma Canós, Avelino (Elsevier, 2017)

[EN] A new route to obtain pillared, disordered or desilicated MWW-type zeolites was developed assisted by quaternary ammonium surfactants with different hydrocarbon tail size acting as swelling agents (C(12)TA(+), C(I6)TA(+), ...
