A simple an efficient approach to confine Cu/ZnO methanol synthesis catalysts in the ordered mesoporous SBA-15 silica

García Trenco, Andrés; Martinez Feliu, Agustin (Elsevier, 2013-10-15)

The ammonia-driving deposition-precipitation (ADP) method has been applied with the purpose of confining active Cu/ZnO methanol synthesis phases inside the pores of the ordered mesoporous SBA-15 silica. Thus, a series of ...
Direct synthesis of DME from syngas on hybrid CuZnAl/ZSM-5 catalysts: New insights into the role of zeolite acidity

García Trenco, Andrés; Martinez Feliu, Agustin (Elsevier, 2012)

[EN] A commercial HZSM-5 zeolite (Si/Al = 16) was submitted to mild acid treatment and partial exchange of H+ by Na+ and Co2+ cations in order to produce samples with different amounts and strengths of Brensted and Lewis ...
New insights into the role of the electronic properties of oxide promoters in Rh-catalyzed selective synthesis of oxygenates from synthesis gas

Prieto González, Gonzalo; Concepción Heydorn, Patricia; Martinez Feliu, Agustin; Mendoza, Ernest (Elsevier, 2011-06-13)

[EN] A series of 2.5% Rh/M@Al2O3 model catalysts were prepared by supporting Rh on high-area gamma-Al2O3, resulting in a surface covered by a monolayer (4.5-7 atoms/nm(2)) of MO promoter oxides (M = Fe, V. Nb, Ta, Ti, Y, ...
Selective room-temperature transformation of methane to C1 Oxygenates by deep UV Photolysis over zeolites

Sastre Calabuig, Francesc; Fornes Seguí, Vicente; Corma Canós, Avelino; García Gómez, Hermenegildo (American Chemical Society, 2011-11)

[EN] Methane can directly be transformed into liquid C 1 oxygenated products with selectivities above 95% at 13% conversion by deep UV photocatalysis, in the presence of H 2O and air. Pure silica zeolites, and more ...
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 ...
Synthesis of acetonitrile from NH3/syngas mixtures on molybdenum nitride: Insights into the reaction mechanism

Kizilkaya, Ali Can; Martinez-Monje, María Elena; Prieto González, Gonzalo (Elsevier, 2024-12-01)

[EN] Owing to their metallic-like surface electronic properties and their capacity to act as reservoirs and solid transfer agents for active nitrogen, transition metal nitrides are interesting as solid catalysts for C-C ...
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% ...
