Summary: Adenosine triphosphate (ATP) and other nucleotides can be irreversibly bound to the metal-organic framework (MOF) MIL-101(Cr). Analysis suggests that ATP is bound to MIL-101(Cr) through the terminal phosphate group with Cr(III) of the framework. The MOF-supported nucleotides can function as stable and reusable enantioselective heterogeneous catalysts in the presence of Cu(II) ions.

Summary: Metal-organic frameworks (MOFs) are promising materials for studying catalytically active structures. By adjusting the nickel loading on MOF NU 1000, the effect of metal nuclearity in MOF-supported catalysts was investigated, and it was found that higher nickel loading led to higher ethylene hydrogenation catalytic rates. This suggests the need for at least two proximal nickel ions for effective catalysis.

Summary: In this study, a highly dispersed Cu catalyst supported on H3PO4-activated coffee biochar (Cu/PBCR-600) is reported to selectively reduce nitroaromatics to corresponding aromatic amines. The Cu/PBCR-600 catalyst exhibits significantly higher TOF values compared to previously reported non-noble and even noble metal catalysts and shows high stability in catalytic recycles. The characterization and activity tests indicate that Cu-0 in Cu/PBCR-600 acts as the active site for the reduction of nitroaromatics, and N, P co-doped coffee biochar selectively adsorbs and activates the nitro group of nitroaromatics.

Summary: Visible-light copper photocatalysis has become a viable technology for sustainable synthetic processes. In this study, a metal-organic framework (MOF)-supported copper(I) photocatalyst was developed for iminyl radical-mediated reactions. The heterogenized copper photosensitizer exhibited higher catalytic activity than its homogeneous counterpart due to site isolation. The immobilization of copper species on MOF supports using a hydroxamic acid linker allowed for high recyclability of the heterogeneous catalysts and the preparation of previously unavailable monomeric copper species through post-synthetic modification on MOF surfaces. This study highlights the potential of MOF-based heterogeneous catalytic systems in addressing challenges in synthetic methodologies and mechanistic investigations of transition-metal photoredox catalysis.

Summary: In this study, the researchers investigated the effect of changing the Cu:Ni ratio on the reactivity of non-oxidative ethanol dehydrogenation using the Zr-based metal-organic framework (MOF) catalyst support, NU-1000. They found that increasing the Ni2+ concentration significantly reduced the activation energy of the reaction by suppressing the onset of Cu reduction. This study demonstrates the potential of using MOFs as catalyst supports to optimize catalyst compositions and understand their impact on catalytic performances.

Summary: Air pollution caused by nitrogen oxides (NO2) from exhaust gas is a long-standing problem that requires new capture and abatement technologies. Electrochemical conversion of NO2 to value-added chemicals is a promising strategy for mitigating imbalances in the global nitrogen cycle. We propose an electrochemical cell based on an aqueous Zn||NO2 system with a nano-NiO catalyst. The cell efficiently captures and converts NO2 to NO2- and value-added NH3 while generating electric power.

Summary: In this study, a series of organic room-temperature phosphorescent (RTP) polymers with tunable color luminescence were prepared by incorporating phosphorescent rotors into polymer backbones. Experimental and theoretical calculations revealed that the various molecular conformations of the monomers are responsible for the excitation wavelength-dependent (Ex-De) RTP behavior. By gaining insights into the underlying mechanism, dynamic control of Ex-De RTP behavior was achieved through thermal energy driven molecular rotations of the monomers. These findings provide new opportunities for controlling the response behaviors of smart-responsive RTP materials through external stimuli rather than conventional covalent modification methods.

Summary: A robust aqueous solid-electrolyte interphase (SEI) is successfully constructed by introducing a ladderized heterocyclic polymer electrode into a water-in-salt electrolyte, enabling ultra-stable dual-ion storage with long-term calendar life. The sophisticated SEI composed of fluorinated/oxygenated species is formed through a proton co-intercalation process, consuming water in the solvation shell of Li+ ions to trigger the decomposition of organic anions. This new SEI formation path is expected to broaden the applications of aqueous SEI and facilitate the design of versatile electrode materials for advanced aqueous Li-ion batteries (ALIBs).

Summary: Inorganic perovskite nanosheets (Cs3Bi2I9, Cs3Sb2I9) are synthesized at the liquid-air interface by drop-casting the precursor solution with the addition of iodine. The thickness and lateral size of the nanosheets can be adjusted through the iodine concentration. The iodine repairs iodine vacancies during perovskite growth, resulting in enhanced optical and optoelectronic properties. The liquid-air interfacial growth of ultrathin perovskites provides flexibility for constructing perovskite-based heterostructures and devices at the atomic scale.

Summary: Due to their low cost and simplified production process, electron-transport layer-free (ETL-free) perovskite solar cells (PSCs) have attracted great attention recently. However, the performance of ETL-free PSCs is still at a disadvantage compared to cells with a conventional n-i-p structure due to the severe recombination of charge carriers at the perovskite/anode interface. In this study, a strategy was reported to fabricate stable ETL-free FAPbI3 PSCs by in situ formation of a low dimensional perovskite layer between the FTO and the perovskite. This interlayer improves energy level alignment between the anode and perovskite, facilitates charge carrier transport and collection, and suppresses charge carrier recombination, leading to ETL-free PSCs with a power conversion efficiency (PCE) exceeding 22% under ambient conditions.
