Highly efficient and reversible CO₂ adsorption by amine-grafted platelet SBA-15 with expanded pore diameters and short mesochannels

Abstract

Amine-grafted mesoporous silica materials with short channels and large pore diameters have been prepared and used to adsorb CO2 efficiently.

Carbon dioxide adsorption by zinc-functionalized ionic liquid impregnated into bio-templated mesoporous silica beads

“…The CO 2 uptake capacities of SALG-AT-EZT3 materials are better or comparable to other impregnated sorbent systems recently reported: amino acid ILs on porous silica (4.8 -8.2 wt%) [58], polyethyleneimine (PEI) on mesocellular foam (MCF) silica (5.5 wt%) [73], and mono-and di-amines grafted on pore-expanded SBA-15 (7.0 and 8.8 wt%, respectively) [75] (see Table S1 in the Supporting data for more extensive comparison). More importantly, we have demonstrated that developing a thin layer of EZT3 onto porous silica beads effectively enhances the uptake kinetics by exposing interaction sites across a large surface area, and facilitating diffusion through the pore network of the support.…”

Molecular sieve supported ionic liquids as efficient adsorbent for CO2 capture

“…Zhang et al 15 successfully prepared ionic liquids supported on SiO 2 , with a CO 2 adsorption efficiency of 1.92 %. 16 Carbon dioxide capture by molecular sieve-supported ionic liquids is one of the promising methods. A molecular sieve was also investigated for CO 2 adsorption because of its large specific surface area and pore volume.…”

SBA-15 as a Support for Nickel-Based Catalysts for Polymerization Reactions

“…Therefore, SBA-15 materials have been applied in many fields, including catalysis, adsorption, separation, medicine and enzyme immobilization. [6][7][8][9][10] The control of its structural properties relies on the synthesis conditions, e.g., temperature, stirring, micelle packaging parameters and the addition of cosurfactants and solvents. These modifications can lead to SBA-15 mesoporous material with different type-morphologies, including spheres, platelets, nanorods, rice shapes and hexagonal columns.…”
