Active Base Hybrid Organosilica Materials based on Pyrrolidine Builder Units for Fine Chemicals Production

Llopis-Perez, Sebastian; Velty, Alexandra; DÍAZ MORALES, URBANO MANUEL (John Wiley & Sons, 2021-12-07)

[EN] The catalytic activity of "pyrrolidine type" fragments included or anchored in the mesoporous silica supports or polymeric frameworks have been fully reported for enantioselective transformation. Nevertheless, low ...
Hybrid organic-inorganic nanoparticles with associated functionality for catalytic transformation of biomass substrates

Coloma-Molina, Alicia; Velty, Alexandra; Díaz, Urbano (The Royal Society of Chemistry, 2023-03-27)

[EN] We present the one-pot synthesis of functionalized organosilica nanoparticles to generate multi-functional hybrid catalysts. Octadecyl, alkyl-thiol and alkyl-amino moieties were used separately and in different ...
Study of the interaction between components in hybrid CuZnAl/HZSM-5 catalysts and its impact in the syngas-to-DME reaction

García Trenco, Andrés; Vidal Moya, José Alejandro; Martinez Feliu, Agustin (Elsevier, 2012-01-05)

[EN] Hybrid CuZnAl(CZA)/HZSM-5 catalysts were prepared by three mixing methods in order to analyze the possible existence of interactions between components and their impact in the STD process, namely: (a) grinding of ...
The impact of zeolite pore structure on the catalytic behavior of CuZnAl/zeolite hybrid catalysts for the direct DME synthesis

García Trenco, Andrés; Valencia Valencia, Susana; Martinez Feliu, Agustin (Elsevier, 2013)

[EN] In this work, the influence of the pore structure of 10-ring zeolites used as the methanol dehydration func-tion in CuZnAl(CZA)/zeolite hybrid catalysts was studied for the direct dimethyl ether (DME) synthesis. Tothis ...
The influence of zeolite surface-aluminum species on the deactivationof CuZnAl/zeolite hybrid catalysts for the direct DME synthesis

García Trenco, Andrés; Martinez Feliu, Agustin (Elsevier, 2014-05-15)

[EN] The influence of the nature and amount of zeolite-surface Al species on the deactivation behavior ofbifunctional CZA/zeolite hybrid catalysts during the direct DME synthesis (260◦C, 4.0 MPa) from syn-gas (66% ...
