چکیده

A new flow-dependent separation selectivity (FDSS) effect was discovered in isocratic HPLC. Significant changes in chromatographic selectivity were achieved by simple variation of the mobile phase flow rate. The FDSS effect was observed for a core-shell stationary phase using silica particles as a core and a Zr-based metal-organic framework (UiO-66) as a shell.

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...

Carbon Dioxide Capture on Metal-organic Frameworks with Amide-decorated Pores

CO2 is the main greenhouse gas emitted from the combustion of fossil fuels and is considered a threat in the context of global warming. Carbon capture and storage (CCS) schemes embody a group of technologies for the capture of CO2 from power plants, followed by compression, transport, and permanent storage. Key advances in recent years include the further development of ne...

Molecular Simulation Studies of Flue Gas Purification by Bio-MOF

As a new branch of MOFs which are composed of biocompatible metal ions and organic ligands, bio-metal-organic frameworks (bio-MOFs) have attracted much attention recently. Bio-MOFs feature multiple Lewis basic sites which have strong interaction with CO2 molecules, thus they have great potential in the separation and purification of gas mixtures containing CO2. In this work, molecular simulatio...

Redox chemistry and metal-insulator transitions intertwined in a nano-porous material.

Metal-organic frameworks are nano-porous adsorbents of relevance to gas separation and catalysis, and separation of oxygen from air is essential to diverse industrial applications. The ferrous salt of 2,5-dihydroxy-terephthalic acid, a metal-organic framework of the MOF74 family, can selectively adsorb oxygen in a manner that defies the classical picture: adsorption sites either do or do not sh...

Comparison of the behavior of metal-organic frameworks and zeolites for hydrocarbon separations.

The objective of this work was to study the adsorption and separation of the most important families of hydrocarbon compounds on metal-organic frameworks (MOFs), in comparison with zeolites. For this purpose, we have selected four probe molecules, each of them representing one of these families, i.e., o- and p-xylene as aromatics, 1-octene as an alkene, and n-octane as an alkane. The separation...
