Available in PDF, EPUB and Kindle. Book excerpt: Metal-Organic Frameworks (MOFs) are crystalline compounds consisting of rigid organic molecules held together and organized by metal ions or clusters. Special interests in these materials arise from the fact that many are highly porous and can be used for storage of small molecules, for example H2 or CO2. Consequently, the materials are ideal candidates for a wide range of applications including gas storage, separation technologies and catalysis. Potential applications include the storage of hydrogen for fuel-cell cars, and the removal and storage of carbon dioxide in sustainable technical processes. MOFs offer the inorganic chemist and materials scientist a wide range of new synthetic possibilities and open the doors to new and exciting basic research. Metal-Organic Frameworks Materials provides a solid basis for the understanding of MOFs and insights into new inorganic materials structures and properties. The volume also reflects progress that has been made in recent years, presenting a wide range of new applications including state-of-the art developments in the promising technology for alternative fuels. The comprehensive volume investigates structures, symmetry, supramolecular chemistry, surface engineering, recognition, properties, and reactions.

This book was released on 2013 with total page 170 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal-Organic Frameworks (MOFs) are nanoporous framework materials with tunable pore size and functionality, and hence attractive for gas separation membrane applications. Zeolitic Imidazolate Frameworks (ZIFs), a subclass of MOFs, are known for their high thermal and chemical stability. ZIF-8 has demonstrated potential to kinetically separate propane/propene in powder and membrane form. ZIF-8 membranes propane-propene separation performance is superior in comparison to polymer, mixed matrix and carbon membranes. The overarching theme of my research is to address challenges that hinder fabrication of MOF membranes on a commercial scale and in a reproducible and scalable manner. 1. Current approaches, are specific to a given ZIF, a general synthesis route is not available. Use of multiple steps for surface modification or seeding causes reproducibility and scalability issues. 2. Conventional fabrication techniques are batch processes, thereby limiting their commercialization. Here we demonstrate two new approaches that can potentially address these challenges. First, we report one step in situ synthesis of ZIF-8 membranes on more commonly used porous [alpha]-alumina supports. By incorporating sodium formate in the in situ growth solution, well intergrown ZIF-8 membranes were synthesized on unmodified supports. The mechanism by which sodium formate promotes heterogeneous nucleation was investigated. Sodium formate reacts with zinc source to form zinc oxide layer, which in turn promotes heterogeneous nucleation. Sodium formate promotes heterogeneous nucleation in other ZIF systems as well, leading to ZIF-7, Zn(Im)2 (ZIF-61 analogue), ZIF-90, and SIM-1 films. Thus one step in situ growth using sodium formate provides a simplified, reproducible and potentially general route for ZIF film fabrication. One step in situ route, although advantageous; is still conventional in nature and batch process with long synthesis time. This limits commercialization, due to scalability and manufacturing cost issues. Taking advantage of coordination chemistry of MOFs and using temperature as driving force, continuous well-intergrown membranes of HKUST-1 and ZIF-8 in relatively short time (15 min) using Rapid Thermal Deposition (RTD). With minimum precursor consumption and simplified synthesis protocol, RTD provides potential for a continuous, scalable, reproducible and commercializable route for MOF membrane fabrication. RTD-prepared MOF membranes show improved separation performances, indicating improved microstructure.

Book excerpt: Metal–organic frameworks are among the most promising novel materials. The concept of MOFs was first introduced in 1990. They were actually initially used in catalysis, gas separation, membranes, electrochemical sensors. Later on, they were introduced as SPE sorbents for PAHs (Polycyclic Aromatic Hydrocarbons) in environmental water samples, then the range expanded to the field of analytical chemistry, both in chromatographic separation and sample preparation, with great success in, e.g., SPE and SPME (Solid Phase Mico-extraction). Since then, the number of analytical applications implementing MOFs as sorbents in sorptive sample preparation approaches is increasing. Τhis is reinforced by the fact that, at least theoretically, an infinite number of structures can be designed and synthesized, thus making tuneability one of the most unique characteristics of MOF materials. Moreover, they have been designed in various shapes, such as columns, fibers, and films, so that they can meet more analytical challenges with improved analytical features.Their exceptional properties attracted the interest of analytical chemists who have taken advantage of the unique structures and properties and have already introduced them in several sample pretreatment techniques, such as solid phase extraction, dispersive SPE, magnetic solid phase extraction, solid phase microextraction, stir bar sorptive extraction, etc.

Download or read book Mixed-matrix Membranes Containing Metal-organic Frameworks for Gas Separations written by Edson V. Perez and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Mixed-matrix membranes for gas separations were prepared using metal-organic framework 5 (MOF-5), copper metal-organic framework (Cu-MOF), and the soluble metal-organic polyhedra 18 (MOP-18) in Matrimid®. The MOF crystals were synthesized as nanocrystals and then activated to obtain high surface areas, comparable to the reported by the corresponding authors. It was found that depending on the organic character of the crystals, the dispersion of the additives in the polymer matrix is improved. MOF-5, having benzene diacetic acid as linker, was loaded up to 30% (w/w) in the polymer matrix and Cu-MOF, having two organic linkers (biphenyl diacetic acid and triethylenediamine), was loaded up to 80% (w/w). The most successful dispersion was achieved with MOP-18 with loadings of up to 80 wt%. Scanning electron microscopy revealed that the morphology of the membranes changed substantially with the types of MOF used. Membranes containing up to 30% (w/w) MOF-5 crystals showed the formation of polymer veins around the nanocrystals suggesting a strong interaction between the two materials. Membranes containing up to 80% (w/w) Cu-MOF crystals did not show the formation of polymer veins due to the improved dispersion of the Cu-MOF nanocrystals. The surface of the membrane showed however a zeolite membrane like morphology consisting of crystal aggregates. Membranes containing up to 80 wt% MOP-18 did not show a defined morphology nor aggregation and exhibited a smooth surface. Gas permeation with pure gases showed that membranes containing MOF-5 and Cu-MOF crystals have affinity for methane and that membranes containing MOP-18 are selective for propylene and methane. Owing to its large pore, membranes containing Cu-MOF showed high permeability values, in the order of hundred of Barrers for most of the gases tested.
