Synthesis and catalytic applications of organo‐functionalized MCM‐41 catalyst: A review

Abstract

In recent times, mesoporous silica sieves gathered considerable attention from a fundamental as well as an applied perspective. Particularly, MCM‐41 has become increasingly popular among researchers because of its chemical flexibility and application in various fields. In addition, MCM‐41‐based materials are currently being extensively studied for their utility as substrates, adsorbents, catalysts, molecular hosts, and ion exchangers. This review article provides a thoughtful analysis of the developments in these areas, particularly emphasizing the recent advance in the functionalization of MCM‐41 via metal complex and their catalytic applications in a variety of reactions such as coupling reactions and oxidation reactions. This review explores the catalytic properties that led to such widespread use, and why there is now an increasing drive to synthesize such a catalytic system.

Comparative Study of Amino-Functionalized Magnetic Mesoporous Arrangements for the Remediation of Persistent Organic Pollutants from Water Using Response Surface Methodology

“…7,8 Within the class of nanomaterials, we can highlight the mesoporous materials, especially those of the M41S family, which have textural and structural features that are compatible to act as adsorbent materials, especially because these materials exhibit high surface area and pore volume, adjustable mesopore diameter, well-ordered architectures, and high thermal and mechanical stability. 9,10 The main members of the M41S family are (i) MCM-41, which has an ordered hexagonal structure; (ii) MCM-50, which has a lamellar architecture; and (iii) MCM-48, with an ordered cubic arrangement. These mesoporous materials have versatility and multifunctionality as main characteristics, so they are applied in the most varied applications in the literature.…”

“…From the perspective of nanotechnology and nanoscience, we can highlight self-assembled nanostructured materials, which have a critical pore diameter ranging from 1 to 100 nm . Therefore, such properties are due to the size and shape of the prepared nanoparticles, and many times can be improved from their fine-tuning of synthesis, when compared to their bulk material (non-nanometric). , Within the class of nanomaterials, we can highlight the mesoporous materials, especially those of the M41S family, which have textural and structural features that are compatible to act as adsorbent materials, especially because these materials exhibit high surface area and pore volume, adjustable mesopore diameter, well-ordered architectures, and high thermal and mechanical stability. , …”

Comprehensive Study on the Adsorption and Degradation of Dichlorodiphenyltrichloroethane on Bifunctional Adsorption–Photocatalysis Material TiO2/MCM-41 Using Quantum Chemical Methods

“…41) is a mesoporous material with a hierarchical structure from a family of silicate and aluminosilicate solids that were first developed by researchers at Mobil Oil Corporation . MCM-41 has attracted considerable interest for possible applications in many fields as diverse as catalysis, drug delivery, adsorption, sensors, and optics due to its high surface area, low mass densities, and well-defined and adjustable pore structure. , It was reported that MCM-41 has a higher adsorption capacity for volatile organic compounds (VOCs) even at high vapor content than silicalite-1 and zeolite Y and commercial activated carbon . MCM-41 derived from rice husk ash was employed for the effective elimination of polycyclic aromatic hydrocarbons, namely, naphthalene, benzo­[ b ]­fluoranthene, benzo­[ k ]­fluoranthene, and benzo­[ a ]­pyrene, from aqueous solutions.…”

Ordered mesoporous silica microspheres for supercritical fluid chromatography

“…On the other hand, the uniform pore size distribution, ordered pore structure, controllable morphology, and large specific surface area could in turn further promote the advantages of SFC. 13 In this context, a detailed study on the performance of monodispersed OMS microspheres in SFC was conducted. The separation mechanism and chromatographic performance of small analytes, and the modification of the pore surface were discussed.…”
