Recent Advances on the Preparation and Catalytic Applications of Metal Complexes Supported-Mesoporous Silica MCM-41 (Review)

Recent developments in state-of-the-art silica-modified catalysts for the fixation of CO2 in epoxides to form organic carbonates

“…131,132 Additionally, this mesoporous silica enables catalytic reactions with bulky substrates. 128,133 Thus, MCM-41 mesoporous silica can be an interesting material as a catalyst for the cycloaddition of CO 2 to epoxides to form cyclic carbonates. In this section, we discuss MCM-41 mesoporous silica functionalized with amines and ionic liquids and MCM-41-supported metallic complexes as catalysts for the synthesis of cyclic carbonates via the chemical fixation of CO 2 in epoxides.…”

Organic dyes supported on silicon-based materials: synthesis and applications as photocatalysts

“…This is explained by the siloxy anions (uSi-O − ) in the structure, which interact with the cations of the surfactant. [98][99][100][101] For instance, Cardoso et al prepared a basic hybrid silica heterogeneous catalyst [CTA]-MCM-41 using cetyltrimethylammonium bromide (CTAB) as directing agent and NH 4 OH as the catalyst of the reaction. 102 The reaction mixture was TEOS : NH 4 OH : CTAB : H 2 O.…”

Progress in Mesoporous Silica Nanoparticles as Drug Delivery Agents for Cancer Treatment

“…Like many breakthroughs, the discovery of mesoporous silica was accidental. M41S exhibited almost non-Brønsted acidity, thin amorphous walls, high surface area, large pore volumes and adjustable pore sizes [ 14 , 15 ]. In M41S, there are three main members, namely, MCM-41, MCM-48 and MCM-50.…”

“…These can be differentiated through their pore geometry where MCM-41 shows hexagonal pore structure, MCM-48 has cubic mesostructured gyroidic phase Ia3d , and MCM-50 exhibits lamellar geometry that consists of silicate or porous aluminosilicate layers separated by surfactant layers [ 16 ]. Among these three, MCM-41 is the most widely studied as MCM-48 and MCM-50 are difficult to obtain and thermally unstable [ 15 ]. Since then, other types of MSNs have been discovered, for example, folded sheet mesoporous material-16 (FSM-16), Santa Barbara Amorphous family (SBA-n), Fudan University material (FDU), Korea Advanced Institute of Science and Technology (KIT), hollow MSNs and others [ 17 ].…”
