Influence of the hydration by the environmental humidity on the metallic speciation and the photocatalytic activity of Cr/MCM-41
(Elsevier, 2014-03)
The influence of the environmental humidity on the Cr species deposited on inorganic supports like<br />MCM-41 silicates was analyzed by UV?vis Diffuse Reflectance (UV?vis RD), Electronic Spin Resonance (ESR) and X-ray ...
Selectively Obtaining ε-Caprolactam from Cyclohexanone Oxime Over Al-MCM-41 Catalysts
(Springer, 2013-02)
Catalysts with Al-MCM-41 structure were prepared by direct hydrothermal synthesis. Nest silanols with weakly acid character, associated to the presence of framework Al, have been identified. These silanols seem be the ...

Comparación de diferentes nanocompuestos mesoporosos, tamiz molecular / hidroxiapatita para la administración de fármacos con el uso de ibuprofeno como fármaco modelo
(Universidad San PedroPE, 2019-09-06)
Los materiales mesoporosos son silicatos, cristalinos, empleados en la catálisis y para la adsorción de diversas moléculas que originan materiales útiles para la química, la farmacia y la medicina. En este trabajo, los ...
Preparation, characterization and activity of CuZn and Cu2 superoxide dismutase mimics encapsulated in mesoporous silica
(Elsevier Science Inc, 2020-06)
Encapsulation of three superoxide dismutase (SOD) functional mimics, [CuZn(dien)2(μ-Im)(ClO4)2]ClO4 (1), [Cu2(dien)2(μ-Im)(ClO4)2]ClO4 (2) (Im = imidazolate, dien = diethylenetriamine), and [CuZn(salpn)Cl2] (3) (H2salpn = ...
Copper mesoporous materials as highly efficient recyclable catalysts for the reduction of 4-nitrophenol in aqueous media
(Pergamon-Elsevier Science Ltd, 2018-08-09)
Two mesoporous-based catalysts with different nominal copper loads (10 and 24% w/w) were prepared from impregnation of the MCM-41 support with copper acetylacetonate: Cu/MCM-41-10 and Cu/MCM-41-24, respectively. Samples ...
