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.

Unravelling the Redox-catalytic Behavior of Ce4+ Metal–Organic Frameworks by X-ray Absorption Spectroscopy

Unravelling the Redox‐catalytic Behavior of Ce4+ Metal–Organic Frameworks by X‐ray Absorption Spectroscopy

Redox change in Ce MOFs: The mechanism by which hexanuclear Ce4+ metal–organic frameworks act as redox catalysts is studied by X-ray absorption spectroscopy. Up to one Ce4+ ion per cluster can be reduced (see picture) with a corresponding outwards radial shift, while not compromising the structural integrity of the framework. This demonstrates the involvement of the metal node in the catalytic cycle and explains the need for TEMPO as redox mediator in two-electron oxidations.

Photocatalytic Overall Water Splitting over MIL-125(Ti) upon CoPi and Pt Co-catalyst Deposition

Photocatalytic Overall Water Splitting over MIL‐125(Ti) upon CoPi and Pt Co‐catalyst Deposition

Time to split: Photocatalytic overall water splitting is realized by taking advantage of the semiconductive and porous properties of MIL-125(Ti). CoPi and Pt are deposited into MIL-125(Ti) in two steps, and the as-prepared MIL-125(Ti)-CoPi-Pt produces stoichiometric H2 and O2 evolution from pure water with no external bias. The co-catalysts CoPi and Pt not only act as reactive sites for oxygen and hydrogen evolution, respectively, but also decrease the overpotential of O2 and H2 evolution from water and improve the photogenerated charge separation efficiency.

Metal-organic Frameworks (MOFs) as Functional Supramolecular Architectures for Anion Recognition and Sensing

Metal‐organic Frameworks (MOFs) as Functional Supramolecular Architectures for Anion Recognition and Sensing

Metal-organic frameworks (MOFs) have experienced a tremendous growth during last few decades as porous crystalline molecular materials. The comprehensive effect of structural diversity, tunability and high surface area makes MOFs suitable for multifarious applications. MOFs can act as potential receptors toward various target components including ionic species, small molecules, solvents, explosives etc. Anion recognition remains important phenomena considering many chemical and biological processes. Ligand designing, incorporation of appropriate function groups and post-synthetic modifications are key strategies in MOFs for selective recognition and scavenging of environmentally toxic and detrimental anions (i. e. cyanide, oxo-anions etc.). The main focus of this personal account is on our research towards development and potential applications of MOFs with special emphasis on selective and sensitive anion sensing.

Stimuli-Responsive Metal-Organic Frameworks with Photoswitchable Azobenzene Side Groups

Stimuli‐Responsive Metal‐Organic Frameworks with Photoswitchable Azobenzene Side Groups

Metal-organic frameworks (MOFs) are nanoporous, crystalline hybrid materials that enable remote control over their key properties by incorporating linker molecules with photoswitchable azobenzene side groups. The applications of these stimuli-responsive nanoporous solids range from switching the adsorption capacity of various gases over remote-controlled release of guest molecules to continuously tunable membrane separation of molecular mixtures.
