STRUCTURAL PROPERTIES OF Cu-MCM-41 AND Cu-Al-MCM-41 (Si/Al=30) CATALYSTS

2002
Cu-MCM-41 and Cu-Al-MCM-41 samples have been obtained by ion exchange of the MCM-41 and Al-MCM-41 matrices prepared by hexadecyltrimethylammonium cloride, tetraethyl orthosilicate, aluminum isopropoxide and an ammonia solution. The aluminum concentration affects the MCM-41 textural properties and large amount of extra-framework aluminum species are ...

Adsorption of basic dyes onto MCM-41

Chemosphere, 2006
The adsorption of two basic dyes, Basic Green 5 (BG5) and Basic Violet 10 (BV10), onto MCM-41 was studied to examine the possible effect of interactions between large adsorbates and MCM-41 on the pore structure stability of MCM-41 and the potential of MCM-41 for the removal of basic dyes from wastewater.

Catalytic ozonation of p-chlorobenzoic acid over MCM-41 and Fe loaded MCM-41

Chemical Engineering Journal, 2012
Abstract Mesoporous MCM-41 and Fe loaded MCM-41 (Fe/MCM-41), which were prepared by hydrothermal and dipping method respectively, were applied as heterogeneous catalysts for the ozonation of p -chlorobenzoic acid ( p -CBA) in aqueous solution. MCM-41 and Fe/MCM-41 were characterized by low and wide angle XRD, atomic absorption spectrometer (AAS) and

Synthesis of highly ordered boron-containing B–MCM-41 and pure silica MCM-41

Microporous and Mesoporous Materials, 1999
Abstract This study deals with the hydrothermal synthesis of highly ordered MCM-41 and B–MCM-41. Four techniques for the generation of MCM-41 were compared: thermal treatment in polypropylene vessels, in static autoclaves, in a stirred autoclave in ovens, and in microwave reactors heated with microwave radiation.

Structure Determination of Spherical MCM-41 Particles

Advanced Materials, 2001
Nitrogen sorption measurements show that template-direct- ed materials obtained via a modified Stber procedure typi- cally have a narrow pore-size distribution. The characteriza- tion of these spherical particles by means of XRD reveals a diffraction pattern that can be indexed as hexagonal. Scanning electron microscopy (SEM) confirms the morphology of

The adsorption aspect of Cu2+ and Zn2+ on MCM-41 and SDS-modified MCM-41

Inorganic Chemistry Communications, 2014
Abstract To determine the interaction mechanism for heavy metal adsorption on functionalized MCM-41 mesoporous silica, both macroscopic and microscopic investigation was performed in this study. Hybrid sorbent material has been developed by modifying MCM-41 with sodiumdodecylsulphate (SDS), named as SDS-MCM-41, and tested for capturing Cu 2 + and Zn
