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.

Xenon Recovery at Room Temperature using Metal–Organic Frameworks

Xenon Recovery at Room Temperature using Metal–Organic Frameworks

Xenon is known to be a very efficient anesthetic gas, but its cost prohibits the wider use in medical industry and other potential applications. The current technology uses a series of adsorbent columns followed by low-temperature distillation to recover Xe; this method is expensive to use in medical facilities. A much more efficient and simpler system is proposed to recover and recycle Xe from simulant exhaled anesthetic gas mixtures at room temperature using metal–organic frameworks (see scheme).

Metal–Organic Framework Material Inhibits Biofilm Formation of Pseudomonas aeruginosa

Metal–Organic Framework Material Inhibits Biofilm Formation of Pseudomonas aeruginosa

Metal–organic framework/chitosan materials are tested for inhibitory bacterial attachment using Pseudomonas aeruginosa. These materials show excellent reductions in bacterial attachment, with ≈85% reduction observed over 6 and 24 h exposure periods. The films also demonstrate reusability as an antibacterial surface. This represents the first use of a water-stable, copper-based metal–organic framework within a polymer for biofilm inhibition.

Explosives in the Cage: Metal–Organic Frameworks for High-Energy Materials Sensing and Desensitization

Explosives in the Cage: Metal–Organic Frameworks for High‐Energy Materials Sensing and Desensitization

Metal–organic frameworks (MOFs) are promising candidates for explosive sensing and desensitization due to their atomically designable and predicable structure, permanent porosity, controllable host–guest interactions, tunable inner-surface environment, and diversity of organic/metal building units. The recent developments, challenges, and perspectives in the strategies for explosive sensing and desensitization by MOFs are comprehensively discussed.

CO2 Cycloaddition to Epoxides by using M-DABCO Metal–Organic Frameworks and the Influence of the Synthetic Method on Catalytic Reactivity

CO2 Cycloaddition to Epoxides by using M‐DABCO Metal–Organic Frameworks and the Influence of the Synthetic Method on Catalytic Reactivity

The route matters: A series of M2(BDC)2(DABCO) (M=Zn, Co, Ni, Cu; BDC=1,4-benzene dicarboxylate; DABCO=1,4-diazabicyclo[2.2.2]octane) metal–organic frameworks (M-DABCO) are prepared by using a solvothermal route, and their activity in the cycloaddition of CO2 to epoxides is investigated. The most active catalyst, Zn-DABCO, is also prepared by using a spray-drying method and the physicochemical properties of both types of Zn-DABCO are compared.

Mesoporous Silica Thin Membranes with Large Vertical Mesochannels for Nanosize‐Based Separation

A biphase stratification growth strategy is developed for fabrication of the well-ordered mesoporous silica thin membranes with large vertical and tunable mesochannels on a variety of substrates. Profiting by centimeter-scale size, tunable, and well-defined vertical mesochannels, the obtained nanofilters based on free-standing mesoporous silica membranes show excellent size-selective separation power for gold nanoparticles mixtures, ovalbumin, and cytochrome c proteins.

Double-sided cubes: Porphyrinic metal–organic frameworks are employed to produce hollow porous carbon nanocubes with homogeneous FeNx and CoNx dopants by pyrolysis. Thanks to this particular structure, high surface area and synergetic contributions between FeNx and CoNx, the optimized FeCo2-NPC-900 exhibits excellent activity, long-term stability, and MeOH tolerance, surpassing the Pt/C, toward oxygen reduction electrocatalysis in both acidic and alkaline media.

Effective, Low‐Cost Recovery of Toxic Arsenate Anions from Water by Using Hollow‐Sphere Geode Traps

Open wide: Hollow-sphere geodes with multiple vast-mouth caves and controllable entrance sizes, based on C-,N-doped NiO (CNN), were effectively used for the capture, extraction, and separation of arsenate (AsO43−) species from water (see figure). The CNN structures showed selective superior removal and trapping capacity from real samples, and have the potential to be excellent adsorbent candidates for environment remediation tools and human healthcare.

Diffusion of Carbon Dioxide and Nitrogen in the Small‐Pore Titanium Bis(phosphonate) Metal–Organic Framework MIL‐91 (Ti): A Combination of Quasielastic Neutron Scattering Measurements and Molecular Dynamics Simulations

Diffusion profusion: The diffusivity of CO2 and N2 in the small-pore metal–organic framework MIL-91(Ti) is explored by using a combination of quasielastic neutron scattering measurements and molecular dynamics simulations. The diffusivities of both CO2 and N2 fall in the range of 10−9 to 10−10 m2 s−1 at 230 to 300 K. At 300 K, the extrapolated N2 diffusivity is about 20 times faster than that of CO2.

Ternary Alloys Encapsulated within Different MOFs via a Self-Sacrificing Template Process: A Potential Platform for the Investigation of Size-Selective Catalytic Performances

Ternary Alloys Encapsulated within Different MOFs via a Self‐Sacrificing Template Process: A Potential Platform for the Investigation of Size‐Selective Catalytic Performances

Flower-like RhCoNi ternary alloys encapsulated within different structured metal–organic frameworks (MOFs) shells are successfully prepared via a self-sacrificing template process with assistance of organic ligands having different coordination ability. Due to the differences between the as-formed ZIF-67(Co) and MOF-74(Ni) shells in the aperture/cavity size, the as-prepared two RhCoNi@MOF composites preform distinct size selectivity during the alkene hydrogenation.

Glycerol Isopropyl Ethers: Direct Synthesis from Alcohols and Synthesis by the Reduction of Solketal

Glycerol Isopropyl Ethers: Direct Synthesis from Alcohols and Synthesis by the Reduction of Solketal

A roundabout route: Solketal was hydrogenated under mild conditions over Pd-doped mesoporous aluminosilicas to yield a mixture of ethers and the isopropyl ether of solketal with high selectivity and yield. For high activity and selectivity, the balance between reductive and acid catalytic functions is essential. The significance of the approach for glycerol hydrophobization is discussed in comparison with the traditional acid-catalyzed route.

Block-Copolymer-Assisted Electrochemical Synthesis of Mesoporous Gold Electrodes: Towards a Non-Enzymatic Glucose Sensor

Block‐Copolymer‐Assisted Electrochemical Synthesis of Mesoporous Gold Electrodes: Towards a Non‐Enzymatic Glucose Sensor

Just a spoonful of sugar: Mesoporous Au films (MpGFs) are synthesized by a simple electrochemical process in the presence of a surfactant, where the mesoporous structure can be controlled by the size of the polymeric micelles. Under optimal potentials, the current response for other interfering molecules is minimal while the current response for glucose is maximal. A linear relationship between the current response and the glucose content is observed over a wide range of concentration.
