Highly ordered mesoporous Al-MCM-41 synthesis through valorization of natural sediment
(American Chemical Society, 2019-02-20)
In this work, natural sediment was used as an alternative and green inorganic source to synthesize valuable structured Al-MCM-41 material by a hydrothermal process. This intertidal sediment contains a mixture of clay ...
Evidencia de puntos calientes a nivel microscópico durante la calcinación de la meso fase Si-MCM-41 mediante SAXS
(Universidad Autónoma Metropolitana (México). Unidad Azcapotzalco. División de Ciencias Básicas e Ingeniería., 2015)
En este estudio se investigó el fenómeno de puntos-calientes a nivel microscópico durante la calcinación del MCM-41, cuantificando la magnitud de la temperatura alcanzada durante la calcinación de la meso fase del MCM- 41; ...
Chromium (VI) removal from water by means of adsorption-reduction at the surface of amino-functionalized MCM-41 sorbents
(Elsevier Inc, 2016-10)
A first study that demonstrates the capability of the amino-functionalized MCM-41 sorbents to reduce Cr(VI) to the less toxic trivalent state is presented. To achieve this aim two mesoporous ordered silica with MCM-41 pores ...
Degradacao termica e catalitica da borra oleosa de Petroleo com materiais nanoestruturados al-mcm-41 e AL-SBA-15
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2012-11-04)
Aiming to reduce and reuse waste oil from oily sludge generated in large volumes by the oil
industry, types of nanostructured materials Al-MCM-41 and Al-SBA-15, with ratios of Si / Al
= 50, were synthesized , and calcined ...
MCM-41-supported vanadium catalysts structurally modified with Al or Zr for thiophene hydrodesulfurization
(Springer, 2019-04)
Vanadium catalysts supported on Al(Zr)-MCM-41-type materials were prepared by impregnation. Textural and structural properties, elemental composition and electronic structure were determined by N2 physisorption, small-angle ...
Purification of H2-rich streams by CO preferential oxidation over Pt nanoparticles supported on ordered porous silica
(Elsevier, 2022-06)
In this work, the performance of mesostructured Pt catalysts is studied for the preferential oxidation of CO in H2-rich environments under a wide range of operating conditions. The catalysts were synthesized by incipient ...
Complexos Níquel-β-diiminas heterogeneizados em MCM-41 e SBA-15: aplicação em oligomerização de olefinas
(Universidade Federal do Rio Grande do NorteBrasilUFRNPROGRAMA DE PÓS-GRADUAÇÃO EM QUÍMICA, 2015-07-31)
The β-diimine ligands 2-(phenyl)amine-4-(phenyl)imine-2-pentene and 2-(2,6-
dimethylphenyl)amine-4-(2,6-dimethylphenyl)imine-2-pentene were combined with the
alkoxysilane group chloropropyltrimethoxysilane (CPTMS) and ...
Effect of nickel loading on hydrogen adsorption capacity of different mesoporous supports
(Springer, 2019-10-03)
Pure siliceous and aluminosilicate mesoporous molecular sieves of MCM-41 type have been used as support for nickel incorporation (2.5 wt%) by wet impregnation method. The hydrogen adsorption capacities at 77 K of these ...
