Metal-Organic Frameworks (MOFs) with open metal sites (OMS) interact strongly a range of polar gases/vapors. However, under ambient conditions, their selective adsorption is generally impaired due to high OMS affinity water. This led previously the privilege selection hydrophobic MOFs for capture/detection volatile organic compounds (VOCs). Herein, we show that this paradigm challenged by metal(III) polycarboxylates MOFs, bearing concentration OMS, as MIL-100(Fe), enabling capture VOCs even...

Understanding the impact of MOF synthesis conditions on production cost is vital in order to have a competitive product with view toward industrial applications. Here, considering benchmark mesoporous iron(III) trimesate MIL-100(Fe) as prototypical example, we show that can reach <30 $/kg if careful selection synthetic route made. Two routes were considered analysis, using sulfate and nitrate iron sources. A new optimized protocol 5 L laboratory pilot-scale reactor based was developed...

There are currently no studies in the literature on use of natural waste marble powder (WMP) resources as inexpensive sorbents for looping cycle CO2 capture. The high volume production is associated with considerable amounts WMP generated byproduct during cutting and polishing procedures, which negatively impacts surrounding environment. main goal innovative idea addressed this study consists investigating if solid wastes from producer sources can be used possible effective materials to...

A novel strategy is proposed to synthesize metal–organic framework (MOF)–gelatin bionanocomposites by taking profit of the thermo-reversible character gelatin and liquid–liquid phase separation process, that is, coacervation. This enables formation based on a series chemically stable Zr4+ dicarboxylate MOFs (UiO-66 MOF-801) differing their hydrophilic–hydrophobic balance chemical functionality. Bionanocomposites with homogeneous uniform distribution MOF particles in matrix as well high...

Abstract An unusual self‐assembly pattern is observed for highly ordered 1500‐nm‐thick films of monodisperse 13‐nm‐sized colloidal PbSe quantum dots, originating from their faceted truncated cube‐like shape. Specifically, self‐assembled dots exhibited attachment to the substrate by &lt;001&gt; planes followed an interconnection through {001} facets in plan‐view and {110}/{111} cross‐sectional‐view, thus forming a cubic superlattice. The thermoelectric properties superlattice thin are...

The understanding of location and accessibility zeolite acid sites is a key issue in heterogeneous catalysis. This paper provides brief overview Fourier transform infrared (FTIR) spectroscopy nuclear magnetic resonance (NMR) characterisation acidity zeolites based on the application test molecules with diverse range basicity kinetic diameters. Many zeolites, including ZSM-5 BEA, have been characterised by monitoring interaction between molecules, such as 1,3,5-triisopropylbenzene, pyridine...

Composites of metal–organic frameworks (MOFs) in polyurethane foams (PUF) are reported to adsorb polar or apolar volatile organic compounds (VOCs), avoiding the problems usually found when handling MOFs powder form. MOF/PUF composites were prepared using MIL-160(Al) and UiO-66(Zr)-(CF3)2 via one step process where particles incorporated during foam matrix formation. Under adjusted conditions, composite materials maintained shape characteristics MOF material, good mechanical stability,...
