Summary: There is a strong demand for materials that can safely and reversibly store the toxic and highly reactive diborane gas at room temperature. This study investigates the interfacial chemistry of diborane storage in the UiO-66-NH2 metal-organic framework (MOF) and reveals a promising pathway for stable and long-term storage of diborane.

Summary: The effects of different metal-organic framework supports on selective hydrogenation catalysts for 1,3-butadiene were studied. Bimetallic Pd-Ni catalysts showed good catalytic performance at low temperature, while supports with alkaline sites reduced catalytic activity but improved butene selectivity.

Summary: A core-shell CuPd@UiO-66-NH2 composite material was synthesized by a double-solvent reduction method, and an N2H4 electrochemical sensor based on this material was constructed. The sensor showed a wide linear range for detecting N2H4 with high sensitivity, making it a potential sensing material for hydrazine detection.

Summary: The photocatalytic degradation of methylparaben using a synthesised metal-organic framework (UiO-66-NH2) under simulated solar light was investigated. The study found that the pollutant can be completely removed in distilled water in 1 hour, but the photocatalytic performance decreased in natural water matrices. The photocatalyst UiO-66-NH2 showed high stability and the degradation mechanism involved photogenerated holes and superoxide radicals.

Summary: Hierarchical Pd/UiO-66-NH2-SiO2 nanofibrous catalytic membranes were fabricated, with the addition of a small amount of water during the solvothermal process resulting in smaller UiO-66-NH2 nanoparticles with micropores and mesopores, providing more surface areas for loading Pd and enhancing active sites, leading to 3 times higher catalytic activity compared to Pd/SiO2. The as-fabricated Pd/UiO-SiO2-3.75 also exhibited good recyclability during five reaction cycles.

Summary: The electrochemical synthesis of hydrogen peroxide using Pt single-atom catalyst confined in NH2-UIO-66 showed excellent selectivity and catalytic performance in the two-electron oxygen reduction reaction. Plasma treatment inhibited Pt particle growth and aggregation and enhanced the interaction between Pt and NH2-UIO-66, leading to enhanced electrocatalytic activity.

Summary: Zirconium-based metal-organic frameworks (Zr-MOFs) with tunable porous structure, simple and scalable preparation process, and high space-time yield were prepared in this study. The CO2 adsorption capacity and selectivity were greatly affected by the defect concentration. The defective G66-NH2-X adsorbents exhibited promising CO2 adsorption and separation performance with excellent sustainability.

Summary: The green synthesis of NH2-UiO-66 MOF with high gravity allowed for efficient drug loading, with doxorubicin physically encapsulated and polymer-coated. The successful tagging of pCRISPR on the MOF surface showed promising results for gene delivery, especially with the use of p(NIPAM)-GMA-UiO-66@DOX@pCRISPR achieving up to 6.4% transfection efficiency. The study also demonstrated the stability of the green MOFs for biomedical applications, despite some partial degradation of the nanomaterials post drug and gene delivery.

Summary: This study focuses on the effect of NH2 modification of UiO-66 on its structure and functional properties. UiO-66-NH2 samples with different contents of aminoterephthalate linkers were successfully prepared. The results show that the specific surface area and the fraction of micropores in UiO-66-NH2 samples decrease with an increase in the aminoterephthalate content. At the same time, the total number of basic sites in UiO-66-NH2 samples increases proportionally with the aminoterephthalate content, but a noticeable decrease in the total number of basic sites and an increase in their strength are observed with higher aminoterephthalate content.

Summary: A series of Bi2Sn2O7/UiO-66-NH2 nanoparticles were synthesized and used as adsorption and photocatalysts for the removal of tetracycline (TC). Among them, BUN16 exhibited excellent adsorption and degradation ability for TC, which was more than 3.6 times higher than that of monomers. The adsorption-enhanced degradation mechanism of BUN16 nanoparticles was investigated, and its performance remained stable after five cycles. The excellent catalytic performance can be attributed to its strong adsorption capacity and the synergistic effect of the Z-type heterojunction charge transfer mechanism.

Summary: For the first time, smart solid base catalysts were developed by anchoring photoresponsive azobenzene motifs onto UiO-66-NH2. The catalytic activity could be tailored by changing the steric hindrance of the catalysts through the isomerization of azobenzene motifs under UV and visible light irradiation.

Cellular and molecular analyses showed good biocompatibility of the nanocarrier in various cell lines. The nanocarrier exhibited targeted drug release capability after encapsulation with leaf extract, with a stimuli-responsive effect in acidic media. Additionally, the nanocarrier demonstrated efficient targeting towards cancer cells, and FAAH-like molecules showed potential as optical biosensors with high selectivity.
