CO2 capture with polyamine-based protic ionic liquid functionalized mesoporous silica

Zhang, Wei; Gao, Erhao; Li, Yu; Bernards, Matthew T.; He, Yi; Shi, Yao

A mesoporous silica supported polyamine-based protic ionic liquid (PIL) sorbent has been prepared by impregnating tetraethylenepentammonium nitrate onto the surface of SBA-15. This innovative hybrid adsorbent exhibits an excellent CO2 adsorption rate in the rate-controlling step of 147?×?10?3 mmol g?1 s?0.5, at least threefold better than other IL-functionalized and amine-modified…

Adsorption of organic pollutants by amine functionalized mesoporous silica in aqueous solution. Effects of pH, ionic strength and some consequences of APTES stability

Otalvaro, Julian Ortiz; Avena, Marcelo; Brigante, Maximiliano

A mesoporous silica with MCM-41 type pore array was synthesized by hydrothermal method and then was functionalized with known amounts of 3-aminopropyltriethoxysilane (APTES) in order to study the selective adsorption towards several species/pollutants. Antibiotics doxycycline hydrochloride (DC) and norfloxacin (NFX), the dye methyl orange(MO) and the pesticide 2,4-dichlorophenoxyacetic acid…

Synergistic Enhancement of CO2 Adsorption Capacity and Kinetics in Triethylenetetrammonium Nitrate Protic Ionic Liquid Functionalized SBA-15

Zhang, Wei; Gao, Erhao; Li, Yu; Bernards, Matthew T.; Li, Younan; Cao, Guanghan; He, Yi; Shi, Yao

A series of triethylenetetrammonium nitrate protic ionic liquid (TNPIL) functionalized, highly ordered mesoporous SBA-15 molecular sieves with different loadings have been synthesized via impregnation. The CO2 capture performance of the hybrid sorbents was evaluated under conditions mimicking a combustion flue gas (15% CO2) over the temperature range of 298–348 K.…

CO2 capture using three-dimensionally ordered micromesoporous carbon

Vorokhta, Maryna; Morávková, Jaroslava; ?imná?ová, Daniela; Pila?, Radim; Zhigunov, Alexander; Švábová, Martina; Sazama, Petr

Adsorption of CO2 on three-dimensionally ordered micromesoporous carbon with a spherical pore structure has been studied using gravimetric and manometric analyses. Adsorptive properties were compared with activated carbon and nanostructured carbon materials such as carbon nanotubes, zeolitic-imidazolate framework-derived carbon, carbon nanohorns and ordered mesoporous carbon materials. The…

Pressure-Driven Solvent Transport and Complex Ion Permeation through Graphene Oxide Membranes

Wang, Kai; Ausri, Irfani R.; Chu, Kyle A.; Seddon, Annela; Tang, Xiaowu (Shirley)

In this paper, an in-depth investigation of three graphene oxide (GO) based membranes—pure GO, Al3+ intercalated GO (Al-GO), and poly(ethylene glycol) (PEG) modified GO (PEG-GO)—is presented. Both Al-GO and PEG-GO membranes have wider interlayer d-spacing compared to pure GO, and the d-spacing size correlates well to the cross-membrane water flux…

Widely tunable persistent micelle templates via homopolymer swelling

Sarkar, Amrita; Thyagarajan, Akshay; Cole, August; Stefik, Morgan

The combination of precision control with wide tunability remains a challenge for the fabrication of porous nanomaterials suitable for studies of nanostructure–behavior relationships. Polymer micelle templates broadly enable porous materials, however micelle equilibration hampers independent pore and wall size control. Persistent micelle templates (PMT) have emerged as a kinetic controlled…

Photocatalytic Template Removal by Non-Ozone-Generating UV Irradiation for the Fabrication of Well-Defined Mesoporous Inorganic Coatings

Reid, Barry; Taylor, Alaric; Alvarez-Fernandez, Alberto; Ismael, Muhamad Hafiz; Sharma, Shatakshi; Schmidt-Hansberg, Benjamin; Guldin, Stefan

The processing of mesoporous inorganic coatings typically requires a high-temperature calcination step to remove organic precursors that are essential during the material assembly. Lowering the fabrication energy costs and cutting back on the necessary resources would provide a greater scope for the deployment in applications such as architectural glass, optical…

Tailoring the Hydrophobicity of Mesoporous Organosilica for Protein Trapping and Supported Catalysis

Osta, Oriana; Bombled, Marianne; Partouche, David; Gallier, Florian; Lubin-Germain, Nadège; Brodie-Linder, Nancy; Alba-Simionesco, Christiane

We propose a method to enhance lysozyme trapping and supported-Copper catalysis when confined in organosilica materials. The direct synthesis presented here allows the control of the silica surface hydrophobicity by uniform introduction of methyl or phenyl groups. As a result, the lysozyme trapping is observed to be 3.2 times more…

Adsorption of norfloxacin on a hexagonal mesoporous silica: isotherms, kinetics and adsorbent reuse

Otalvaro, Julián Ortiz; Avena, Marcelo; Brigante, Maximiliano

The adsorption of the antibiotic norfloxacin (NFX) on MCM-41 type mesoporous silica has been studied in batch experiments by performing adsorption kinetics and isotherms under different conditions. Regeneration of the adsorbent and reuse studies were also carried out and are discussed. On the one hand, the adsorption is very fast…

Enhanced functional properties of biopolymer film incorporated with curcurmin-loaded mesoporous silica nanoparticles for food packaging

Wu, Chunhua; Zhu, Yang; Wu, Tiantian; Wang, Lin; Yuan, Yi; Chen, Jicheng; Hu, Yaqin; Pang, Jie

Curcumin loaded mesoporous silica nanoparticle (SBA-15) was incorporated into chitosan (CS) film to improve the functional properties of pure CS film. Curcumin was loaded into SBA-15 (SBA-15-Cur) through a rotavapor method. The structural properties of SBA-15-Cur were characterised in detail by small-angle X-ray scattering, fourier transform-infrared (FT-IR) spectroscopy, transmission electron…
