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 ...

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 = ...

Ti-MCM-41 catalysts were prepared incorporating Ti by post-synthesis methods: wetness and wet impregnation of MCM-41 mesoporous solid. The samples were characterized by XRD at low angle, UV-vis DRS, Raman spectroscopy, ...

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 ...

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 ...

Metalloporphyrin catalysts are able to carry out selective oxidation of organic substrates with several oxidizing agents. Recently, mesoporous materials have been studied as supports because they present high specific ...

The mesoporous molecular sieves of the MCM-41 and FeMCM-41 type are considered promissory as support for metals used as catalysts in oil-based materials refine processes and as adsorbents for environmental protection ...

Mesoporous silicate (MCM-41) materials, modified with CuII, FeIII or AlIII were prepared by a hydrothermal method and were characterized by nitrogen adsorption at 77 K, X-ray powder diffraction (XRD), transmission electron ...
