چکیده

Incorporation of Li cations into MOFs by either of two methods, chemical reduction or cation exchange, significantly improves the CO2/CH4 selectivity. While the selectivity enhancement by the chemical reduction seems to come from favorable displacement of catenated frameworks, the selectivity improvement by the Li cation exchange comes from enhanced solid–gas interactions. 2010 Elsevier Inc.

Synthesis and Selective CO2 Capture Properties of a Series of Hexatopic Linker-Based Metal-Organic Frameworks.

Four crystalline, porous metal-organic frameworks (MOFs), based on a new hexatopic linker, 1',2',3',4',5',6'-hexakis(4-carboxyphenyl)benzene (H6CPB), were synthesized and fully characterized. Interestingly, two members of this series exhibited new topologies, namely, htp and hhp, which were previously unseen in MOF chemistry. Gas adsorption measurements revealed that all members exhibited high ...

Enhancement of Methane Adsorption by Lithium Doping into Metal-Organic Framework Cu-BDC

Copper (II) carboxylate, (Cu-BDC), metal-organic-framework (MOF) has been synthesized undersolvothermalconditions and used as a new adsorbent for the methane. The Lithium doping intoCu-BDC, (Li-Cu-BDC), is made by impregnating Cu-BDC with an ethanol solution ofLiNO3, followed by heat treatment in vacuum. The adsorbent was characterized by X-ray diffraction (XRD), Fourier transform infrared ...

Evaluation of the Metal-Organic Frameworks MIL-47, MIL-53 and Cu3(BTC)2 for the Adsorptive Separation of Molecular Mixtures

A new class of microporous adsorbents, the metal-organic frameworks was recently developed. Despite their promising characteristics, not much is known about their adsorption behaviour, certainly for mixtures. In this work, vapour and gas phase adsorption and separation of (i) linear and branched alkanes, cyclohexane and benzene, (ii) C8 alkylaromatic compounds and (iii) CO2 and CH4 is studied o...

Enhancement of CO2/CH4 Adsorptive Selectivity by Functionalized Nano Zeolite

In this work, we have modified a synthesized Y-type zeolite (Si/Al = 2.5), with three different amines to investigate of the influence of adsorbent’s surface modification on CO2 selectivity over CH4. The pristine and amine-functionalized NaY zeolites were characterized by X-ray diffraction (XRD), thermal gravimetric analysis (TGA), Fourier transform infrared (FT-IR), and N2 adsorption. The resu...

Comment on comparative molecular simulation study of CO2/N2 and CH4/N2 separation in zeolites and metal-organic frameworks.

In this work, a systematic molecular simulation study was performed to compare the separation of CO2/N2 and CH4/N2 mixtures in two different classes of nanoporous materials, zeolites, and metal-organic frameworks (MOFs). For this purpose, three zeolites (MFI, LTA, and DDR) and seven MOFs (Cu-BTC, MIL-47 (V), IRMOF-1, IRMOF-12, IRMOF-14, IRMOF-11, and IRMOF-13) were chosen as the representatives...
