Summary: The removal of zinc ions from water was studied using two types of ordered mesoporous silica (SBA-15 and SBA-16). Both materials were modified with APTES and EDTA through post grafting methods. The modified adsorbents were characterized by various analytical techniques, and the structural integrity was maintained. Optimal adsorption conditions and maximum adsorption capacity were determined through experimental tests, and the regenerated adsorbent showed no significant decline in adsorption efficiency.

Summary: Naproxen was impregnated into mesoporous SiO2 SBA-15 using the Supercritical Solution Impregnation (SSI) technique. The percentage of naproxen impregnated decreased with increasing CO2 density and with the addition of ethanol, ethyl acetate or menthol. The impregnated naproxen on SiO2 became amorphous and showed interaction with SiO2 support. Release tests showed a sustained release system with a slower rate compared to pure naproxen due to the interaction and diffusion of the drug.

Summary: This paper investigates the adsorption performance of silver-modified mesoporous materials in removing thiophenic compounds. The results show that the adsorption of thiophene by the sorbents involves S-Ag and pi complexation reactions, and the adsorption efficiency is greatly affected by benzene. XPS analysis reveals that silver interacts strongly with the carrier and forms Ag-O-Si bonds as the active centers for thiophenic compounds. The Mulliken charges of sulfur atoms have an impact on the interactions between silver and thiophene sulfur compounds.

Summary: The removal of phosphate from water is crucial for protecting the ecological environment due to the widespread use of phosphorus fertilizers causing water deterioration. In this study, calcium carbonate-loaded mesoporous SBA-15 nanocomposites with different Ca:Si molar ratios (CaAS-x) were synthesized as effective phosphorus adsorbents. Various characterization techniques were used to examine the structure, morphology, and composition of the nanocomposites. The results showed that increasing the Ca:Si molar ratio improved the phosphate removal capacity, with CaAS-0.55 exhibiting the highest adsorption capacity. The mesoporous CaAS-0.55 nanocomposite demonstrated fast and efficient removal of high concentrations of phosphate in contaminated wastewater.

Summary: A visible light photosensitizing metal-organic cage is used as an artificial supramolecular reactor to control the reaction of aryl radicals with terminal olefins, resulting in the selective transformation of geometrically defined E/Z-alkenes. The hydrophobic cage efficiently includes aromatic substrates, promoting Meerwein arylation and protecting E-isomeric products, while benzonitrile induces efficient E -> Z isomerization. In addition to pi-pi stacking, hydrogen bonding and halogen bonding interactions play a role in controlling the arylation of aliphatic terminal olefins. This switchable cage-confined arylation catalysis has been demonstrated in the syntheses of Tapinarof and a marine natural product, achieving controllable E/Z selectivity.

Summary: Here, we demonstrate the ability of a dual-purpose periodic mesoporous organosilica (PMO) probe to track the complex chlorinated paraffin (CP) composition in living animals. The PMO probe serves as an adsorbent-assisted atmospheric pressure chemical ionization Fourier-transform ion cyclotron resonance mass spectrometry (APCI-FT-ICR-MS) platform and an in vivo sampling device. The PMO probe enables synchronous solvent-free ionization and in-source thermal desorption of CP homologues, resulting in improved detection limits and the identification of potential CP metabolites in living fish.

Summary: The host-guest interaction and microenvironment around the Re complex in two metal-organic frameworks, ZIF-8 and UiO-66, were investigated. It was found that ZIF-8 provided a confined space for Re through electrostatic interaction, while UiO-66 offered a relaxed space through coordination interaction. The Re@ZIF-8 exhibited a significantly higher turnover number for CO2 photoreduction compared to Re@UiO-66, which was attributed to the promotion of electron transfer in Re@ZIF-8 and hindrance in Re@UiO-66. The spatial confinement in Re@ZIF-8 stabilized charged intermediate species during CO2 activation, whereas Re-triethanolamine adducts prevailed in Re@UiO-66 due to the accessibility of the Re complex. This study demonstrates the feasibility of altering CO2 activation pathway through the microenvironment of a molecular catalyst in artificial photosynthesis.

Summary: Enzymes, as exceptional natural catalysts, play vital roles in life-sustaining biotransformations due to their exquisite 3D structures. However, their flexibility makes them vulnerable in non-physiological environments, hindering their large-scale industrial applications. This study presents a new bottom-up strategy for enzyme encapsulation using a hydrogen-bonded organic framework (HOF-101), allowing for the encapsulation of various enzymes within a highly crystalline scaffold. Compared to other methods, this enzyme-triggering HOF-101 encapsulation is easy to operate and offers higher loading efficiency, with a well-arranged structure and mesochannels that enhance mass transfer and understanding of biocatalytic processes.

Summary: Simultaneous removal of ethane and acetylene from a C2-gases mixture for ethylene purification is challenging due to their similar properties. Multifunctional metal-organic frameworks (MOFs) were constructed via dynamic spacer installation (DSI) to optimize the pore-nanospaces for efficient C2H4 isolation. The optimized MOF showed four times higher adsorption capacities for ethane and acetylene than the prototype. This study demonstrates a promising protocol for screening MOFs through porenanospace engineering for challenging separations.

Summary: Photocatalytic reduction of excess CO2 in the atmosphere to value-added chemicals by visible light can be achieved using a trinuclear Re(I)-coordinated organic cage (Re-C-4(R)) as the supramolecular photocatalyst. The Re-C-4(R) exhibits higher catalytic activity and CO2 adsorption ability compared to its mononuclear analogue Re-bpy, due to its covalent linkage, cryptand structure, and multiple amine groups. The trinuclear cryptate structure of Re-C-4(R) also facilitates electron transfer efficiency during CO2 reduction, as indicated by its shorter decay lifetimes in transient absorption and photoluminescence decay spectra compared to Re-bpy.

Summary: This contribution comprehensively investigates the biomineralization of zeolite imidazole frameworks for one-step synthesis of an enzyme-MOF biocomposite. The study reveals that the biomineralization ability depends on the ZIF organic linker, and the biocatalytic function is highly related to the ZIF mineral species and their microstructures. Additionally, the protective effect of ZIF mineral on the hosted enzyme is associated with the synergistic effect of size dimension and chemical microenvironment of the ZIF pores.
