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.

Yolk–Shell MnO@ZnMn2O4/N–C Nanorods Derived from α-MnO2/ZIF-8 as Anode Materials for Lithium Ion Batteries

Yolk–Shell MnO@ZnMn2O4/N–C Nanorods Derived from α‐MnO2/ZIF‐8 as Anode Materials for Lithium Ion Batteries

A one-step carbonizing strategy is applied to prepare yolk–shell MnO@ZnMn2O4/N–C nanorods for lithium ion batteries. The predominant electrochemical performance originates from the unique yolk–shell nanorod structure and the coating effect of N–C, which buffers volume change and provides short ion diffusion distance and direct current pathways to accelerate reaction kinetics and improve electrical conductivity.

Highly Crystalline Mesoporous Silicon Spheres for Efficient Visible Photocatalytic Hydrogen Evolution

Highly Crystalline Mesoporous Silicon Spheres for Efficient Visible Photocatalytic Hydrogen Evolution

Highly crystalline mesoporous silicon spheres are developed through a modified salt-assisted aerosol synthesis, and overcome the limitation of particulate silicon in photocatalytic H2 evolution. The developed silicon structures exhibit high efficiency in visible-light-driven H2 production from water, which can otherwise be virtually impossible to attain by counterpart materials.

Neon-bearing ammonium metal formates: formation and behavior under pressure

The incorporation of noble gas atoms, in particular neon, into the pores of network structures is very challenging due to the weak interactions they experience with the network solid. Using high-pressure single-crystal X-ray diffraction, we demonstrate that neon atoms enter into the extended network of ammonium metal formates, thus forming compounds Nex[NH4][M(HCOO)3]. This phenomenon modifies the compressional and structural behaviors of the ammonium metal formates under pressure. The neon atoms can be clearly localized within the center of [M(HCOO)3]5 cages and the total saturation of this site is achieved after 1.5 GPa. We find that by using argon as the pressure-transmitting medium, the inclusion inside [NH4][M(HCOO)3] is inhibited due to the larger size of the argon. This study illustrates the size selectivity of [NH4][M(HCOO)3] compounds between neon and argon insertion under pressure, and the effect of inclusion on the high-pressure behavior of neon-bearing ammonium metal formates.

Ground control: Molecules attached to surfaces control the dielectric properties of liquid–solid interfaces and modulate chemical processes in the same way solvents do. Quantitative relationships are established between nature/surface density of organic groups and interface polarities.

Amide‐CO2 Interaction Induced Gate‐Opening Behavior for CO2 Adsorption in 2‐Fold Interpenetrating Framework

A flexible amide-containing metal-organic framework is comprised of a 2-fold interpenetrating network with amide groups exposed in the channels. The regular arrangement of the amide groups provided significant amide-CO2 and possible amide-CO2-CO2 cooperative effects that enhanced the adsorption of CO2 molecules. Significantly, the findings show that the amide-CO2 interactions induced gate-opening behavior.

This MOF shows the color-changing behavior from orange-red to yellow-brown depending on the structural decomposition due to the removal of guest solvents from the pores of MOF.

A New Paddlewheel‐Type Dirhodium‐Based Metal‐Organic Framework with Deprotonated 2,6‐Bis(2‐benzimidazolyl)pyridine

Two different crystals, orange-red chips (1) and purple blocks (2), are obtained via the solvothermal reaction of [Rh2(OAc)4(H2O)2] (OAc=acetate) and 2,6-bis(2-benzimidazolyl)pyridine (bzimpy2H) in EtOH. Single crystal X-ray diffraction analyses revealed that complex 1 forms a porous two-dimensional framework constructed from [Rh2(OAc)4] and [Rh(bzimpyH)(bzimpy)], whereas complex 2 forms a bis-bzimpy2H-adducted discrete complex, [Rh2(OAc)4(bzimpy2H)2]. Complex 2 shows the color-changing behavior due to the presence of the guest solvents in the pores.

Selective Heterogeneous C-H Activation/Halogenation Reactions Catalyzed by Pd@MOF Nanocomposites

A directed heterogeneous C-H activation/halogenation reaction catalyzed by readily synthesized Pd@MOF nanocatalysts was developed (see scheme). The heterogeneous Pd catalysts used were a novel and environmentally benign Fe-based metal–organic framework (MOF) (Pd@MIL-88B-NH2(Fe)) and the previously developed Pd@MIL-101-NH2(Cr). Very high conversions and selectivities were achieved under very mild reaction conditions and in short reaction times.
