Summary: A metal-organic framework (MOF) called UiO66-4F has been designed and synthesized with strong electron-withdrawing groups, which greatly improves the performance of MOF-based triboelectric nanogenerators (TENGs). The UiO-66-4F@PDMS TENG exhibits a power density 77.5 times higher than that of a regular PDMS TENG and achieves a record voltage output of 937 V in MOFs-based TENGs. It also has high flexibility, good transparency, and can charge commercial capacitors and power commercial LEDs.

Summary: The use of conductive MOFs (c-MOFs) in zinc-based batteries has been explored due to their superior conductivity compared to other MOFs. This paper discusses the transfer mechanisms and electron transport of c-MOFs, as well as various methods for their preparation. The applications and future prospects of c-MOFs in different types of zinc-based batteries are also discussed.

Summary: Dyed wastewater has a serious impact on living organisms and must be treated before being released into the environment. Metal organic frameworks (MOFs) have been proposed as the most effective method for dye wastewater removal due to their high adsorption capacity and adjustable pore diameter and surface morphology. This study aims to evaluate the effectiveness of different types of MOFs in dye separation from wastewater and includes the examination of adsorption isotherms, kinetics, and characterization studies. The desorption and reuse of MOFs are also considered.

Summary: A new C2H2 adsorption trap (UPC-80) constructed by 4-fold interpenetration nets is reported, which shows high adsorption selectivities of 6.34 and 4.78 for C2H2/CO2 and C2H2/C2H4, respectively. Laboratory-scale fixed-bed breakthrough experiments confirm the efficient separation ability of UPC-80 towards the C2H2/CO2 and C2H2/C2H4 gas mixtures, with negligible capacity loss. Theoretical simulations attribute the good separation performance to the anchoring of C2H2 by two Tb2(COO)6 clusters in adjacent interpenetration nets and the strong electrostatic interaction.

Summary: A facile strategy to construct heteroatom-induced interfaces and develop titanium-organic frameworks (MOF-902) @ thiophene-based covalent triazine frameworks (CTF-Th) nanosheets S-scheme heterojunctions with controllable oxygen vacancies (OVs) is reported. The enhanced interfacial charge separation and transfer induced by moderate OVs in the pre-designed S-scheme nanosheets was validated using various analytical techniques. The heterostructures exhibited improved efficiency in photocatalytic reactions and an extended scope of substrates, outperforming state-of-the-art photocatalysts.

Summary: This study investigates the gas-solid reaction of nitric oxide with the metal-organic framework Cu-I-ZrTpmC* and identifies an unusual chelating N2O2.- intermediate using in situ spectroscopies and density functional theory simulations. The results highlight the advantage of site-isolation in metal-organic frameworks (MOFs) for studying important reaction intermediates and provide a mechanistic scenario compatible with the proposed one-electron couple in these enzymes.

Summary: Metal-organic framework (MOF) and covalent organic framework (COF) hybrid materials, with their complementary advantages and suitable band gap, have attracted significant attention in photocatalysis research. The formation of a novel sunflower-like strong pi-pi bond stacking MOF@COF hybrid platform was achieved by introducing a preformed synthetic COF into the MOF precursor solution and modulating its morphology. The synthesized MOF on the COF hybrid platform exhibited excellent catalytic activity in the photocatalytic CO2 reduction reaction under simulated sunlight, with impressive CH4 yieldrate, apparent quantum yield, and methane selectivity.

Summary: This study utilized a covalent-integration strategy to construct a series of multivariate Ti-MOF/COF hybrid materials, which exhibited excellent visible-light utilization, suitable band gap, and high surface area for enhanced visible-light-driven photocatalytic H-2 evolution performance. The resulting composites showed significantly improved H-2 evolution rates compared to individual components, suggesting a promising new approach for highly efficient photocatalysts beyond H-2 evolution.

Summary: The sensing and monitoring of toxic oxo-anion contaminants in water are important to biological and environmental systems. A hydro-stable SIFSIX metal-organic framework, SiF6@MOF-1, with exchangeable SiF62- anion in its pore is designed and synthesized for selective detection of toxic Cr2O72- oxo-anion in an aqueous medium. The mechanism behind the selective detection is revealed through single-crystal-to-single crystal fashion and density functional theory calculations.
