Mesoporous Materials

Interest in mesoporous materials (IUPAC definition: pore size 2–50 nm) has developed dramatically over the last few years, not least because the pore structure of these materials provides an extremely large surface area within a relatively small volume of material. This makes the materials suitable, for example, for catalysis, chemical sensors, and molecular separation.

The following is a selection of recent articles in this field from Angewandte Chemie, Chemistry—A European Journal, Advanced Materials, Advanced Functional Materials, and the European Journal of Inorganic Chemistry.

Encapsulating Palladium Nanoparticles Inside Mesoporous MFI Zeolite Nanocrystals for Shape‐Selective Catalysis

Shape-selective reactions over a palladium nanoparticle (Pd NP) based catalyst were achieved by integrating Pd NPs inside mesoporous silicalite-1 nanocrystals.

Effects of the Framework and Mesoporosity on the Catalytic Activity of Hierarchical Zeolite Catalysts in Benzyl Alcohol Conversion

Effects of the Framework and Mesoporosity on the Catalytic Activity of Hierarchical Zeolite Catalysts in Benzyl Alcohol Conversion

Inside out: The effects of the framework and mesoporosity on the catalytic activity of hierarchical zeolite catalysts are investigated by studying the catalytic performance of three-dimensionally ordered mesoporous imprinted zeolites and comparing them to other microporous and mesoporous catalysts with a high external surface area. The mesoporosity in MFI and BEA zeolites can enhance the catalytic performance of the zeolite catalysts for the self-etherification of benzyl alcohol.

Importance of Micropore–Mesopore Interfaces in Carbon Dioxide Capture by Carbon‐Based Materials

The impact of mesoporosity: Mesoporous carbon materials (Starbons®) derived from waste biomass show an enhanced carbon dioxide capture capacity and an enhanced selectivity for carbon dioxide compared to microporous activated carbon.

Metal-Organic Gel Material Based on UiO-66-NH2 Nanoparticles for Improved Adsorption and Conversion of CO2

Metal-organic frameworks (MOFs) including UiO-66 series show potential application in CO2 adsorption and conversion. Herein, we report the first tetravalent metal-based metal-organic gels based on Zr(IV) and 2-aminoterephthalic acid (H2BDC-NH2). ZrBDC-NH2 gel materials are based on UiO-66-NH2 nanoparticles, and can be easily prepared under mild conditions (80 oC for 4.5 h). ZrBDC-NH2-1:1-0.2 gel material shows high surface area (up to 1040 m2 g-1). ZrBDC-NH2-1:1-0.2 has a superior performance in CO2 adsorption (using dried material) and conversion (using wet gel) arising from its combined advantages of gels and UiO-66-NH2 MOF. ZrBDC-NH2-1:1-0.2 dried material shows 38% higher capture capacity for CO2 at 298 K than microcrystalline UiO-66-NH2. It shows high IAST selectivity (71.6 at 298 K) for a CO2/N2 gas mixture (molar ratio 15 : 85). Furthermore ZrBDC-NH2-1:1-0.2 gel shows activity as a heterogeneous catalyst in chemical fixation of CO2 and an excellent catalytic performance was achieved for the cycloaddition of atmospheric pressure of CO2 to epoxides under 373 K. In addition, the gel catalyst can be reused for multiple cycles and no considerable loss of catalytic activity was observed after five runs.

Direct Evidence of CO2 Capture under Low Partial Pressure on a Pillared Metal–Organic Framework with Improved Stabilization through Intramolecular Hydrogen Bonding

Direct Evidence of CO2 Capture under Low Partial Pressure on a Pillared Metal–Organic Framework with Improved Stabilization through Intramolecular Hydrogen Bonding

Capturing carbon dioxide: FJU-40-NH2 is shown to be the first MOF for which the stability is controlled through intramolecular hydrogen-bonding interactions. Direct structural evidence obtained under low CO2 partial pressure suggests that: 1) the CO2 loading mechanism into the cages depends on CO2 partial pressure; 2) FJU-40-NH2 can capture CO2 directly from air (see figure); and 3) the triazolate C−H groups, rather than amino groups, are the predominant functional sites here.

Wavelength-Tunable Microlasers Based on the Encapsulation of Organic Dye in Metal–Organic Frameworks

Wavelength‐Tunable Microlasers Based on the Encapsulation of Organic Dye in Metal–Organic Frameworks

A wavelength-tunable microlaser has been realized based on the controlled intramolecular charge transfer (ICT) process in dye-encapsulated metal–organic framework (MOF) material. The confinement effect of MOFs is beneficial for low-threshold lasing. By effectively controlling the polarity of the MOF pores, the population distribution between the locally excited and ICT states is continuously modulated, thus achieving broadband tunable MOF-based microlasers.

Separation of Light Hydrocarbons through Selective Molecular Exclusion by a Microporous Metal-organic Framework

Zn2(sdc)2(bpe) (Compound 1, sdc = 4,4'- Stilbenedicarboxylate, bpe = 1,2-Bis(4-pyridyl)ethane)), a doubly interpenetrated, pillar-layer microporous metal-organic framework has been solvothermally synthesized and structurally characterized by single X-ray diffraction. The structure features a common Zn2(COO)4 paddle-wheel building unit. Compound 1 undergoes structural change upon solvent removal. The activated phase (Compound 2) possesses permanent porosity, excellent thermal/moisture stability and interesting hydrocarbon adsorption property. Gas adsorption experiments show that compound 1 selectively adsorbs saturated/unsaturated C2 hydrocarbons but excludes C3 or C4 hydrocarbons at room temperature. We have collected single component adsorption isotherms of six lighthydrocarbons and calculated adsorption selectivities of various binary hydrocarbon mixtures by Ideal Adsorbed Solution Theory (IAST). The results show that compound 1 possesses remarkably high selectivity towards C2 over C3/C4 hydrocarbons and the separation is achieved by selective molecular exclusion.

Poly(ethylenimine)-Functionalized Monolithic Alumina Honeycomb Adsorbents for CO2 Capture from Air

Poly(ethylenimine)‐Functionalized Monolithic Alumina Honeycomb Adsorbents for CO2 Capture from Air

Clean air powder: Amine-functionalized honeycomb monoliths are prepared, characterized, and compared to similar powder sorbents for their application in the removal of CO2 from air. The monoliths have a volumetric capacity that exceeds that of a sorbent considered in a previous modeling study. CO2 extraction directly from air with chemicals could have operating costs as low as $100 per ton, which thus asserts the promise of this technology in CO2 extraction directly from air with chemicals.

Void Engineering in Metal–Organic Frameworks via Synergistic Etching and Surface Functionalization

A top-down strategy to construct various hollow metal–organic frameworks (MOFs) is reported via synergistic etching and surface functionalization by using phenolic acid. Simultaneous surface modification not only allows precise etching inside the MOFs, but also results in a metal–phenolic coating on the MOFs. The metal–phenolic coating endows the MOFs with near infrared laser responsiveness.

Owing to the high content of pyridinic-N groups, the CO2/N2 selectivity on the four synthesized MOFCs is also high (see figure).

This review provides an update on various metal–organic framework (MOF)-based chemical sensors and their classification on the basis of different mechanisms of luminescent (“turn-on” and “turn-off”) and optoelectronic responses (see figure). There are many examples of turn-off detection, but far fewer of turn-on detection. MOF-based electrochemical sensors, in particular, are in their infancy.

Assembling Metal–Organic Frameworks in Ionic Liquids and Supercritical CO2

Assembling Metal–Organic Frameworks in Ionic Liquids and Supercritical CO2

Being green: Ionic liquids (ILs) and supercritical carbon dioxide (scCO2) are considered to be green solvents with tunable properties. They have been shown to be ideal media for the synthesis of a variety of metal–organic frameworks (MOFs) with desirable structures and properties (see figure). This review describes advances in MOF synthesis in ILs, scCO2, and IL/scCO2 systems.
