Selective oxidation of benzyl alcohol through eco-friendly processes using mesoporous V-MCM-41, Fe-MCM-41 and Co-MCM-41 materials
(Elsevier Science, 2017-07-25)
MCM-41 nanostructured materials modified with Vanadium, Iron and Cobalt were synthesized by a hydrothermal method. The catalysts were characterized by XRD, UV–Vis-DR, ICP-OES and N2 adsorption. All the catalysts showed ...
Evaluación de la capacidad de captura de CO₂ mediante materiales mesoporosos de sílice modificados
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2015)
La capacidad de captura de CO₂ a baja presión (<100 kPa) y baja temperatura (298 K) se investigó en cuatro materiales mesoporosos MCM-41, uno sin modificación y tres modificados por síntesis directa con un metal (M); la ...
Thermogravimetric investigations during the synthesis of silica-based MCM-41
(Kluwer Academic Publ, 2001-01-01)
MCM-41 material was synthesized starting from hydrogel containing colloidal fumed silica, sodium silicate, cetyltetramethylammonium bromide (CTMABr) as surfactant, and distilled water as solvent. These reactants were mixed ...
Iron and copper immobilised on mesoporous MCM-41 molecular sieves as catalysts for the oxidation of cyclohexane
(Elsevier Science BvAmsterdamHolanda, 1999)
Ni/MCM-41 y Co/MCM-41 como catalizadores Fenton heterogéneos en la degradación de tartrazina
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2021)
MCM-41 con Ni y Co soportados (a diferentes relaciones Si/metal) se prepararon con la finalidad de estudiar su efecto en la degradación de tartrazina (Amarillo-5) en solución acuosa con ayuda de peróxido de hidrógeno en ...
Dependence of the Structural Stability of MCM-41 on the Impregnating Iron Solution
(Springer, 2003-06)
The MCM-41 mesoporous material was chosen as support of very small iron oxide particles. To study the preparation conditions that allow to preserve the support structure four samples were prepared. The solids were characterized ...
Synthesis and magnetic characterization of magnetite particles embedded in mesoporous MCM-41
(Elsevier Science, 2006-11)
A solid of 7.7 wt% iron-loaded MCM-41 was obtained by impregnating the mesoporous material with an Fe-carrying organic salt after subjecting the matrix to a silylation treatment. The Mössbauer and magnetic results show ...
