Summary: Physisorption is considered a promising energy-saving technique for carbon dioxide (CO2) sequestration, and in this study, a novel ultramicroporous metal-organic framework ZU-301 was developed for efficient CO2 capture from humid gas with high selectivity and moderate adsorption enthalpy. The unique structure of ZU-301, featuring high-density oxalate anions and hydrophobic methyls in a one-dimensional pore channel, allows for excellent separation selectivity and low affinity to moisture. Moreover, ZU-301 demonstrates good chemical stability and high efficiency in CO2/CH4 and CO2/N-2 separation under elevated temperature and humid conditions, showing significant scientific and industrial value.

Summary: An approach to prepare previously unknown 5- and 7-azachromones was developed by condensing isomeric 2(4)-acetyl-3-hydroxypyridines with ethyl formate. The physicochemical studies showed that the lipophilicity and basicity were minimally affected by the introduction of the nitrogen atom, making the azachromones direct analogs of the parent chromone. The utility of azachromones was demonstrated by synthesizing a series of 3,4-dihydro-2H-pyrano[3,2-b]pyridines and -[2,3-c]pyridines.

Summary: Phenoxyl radicals derived from phenols have been harnessed for photocatalysis due to their stability and mild oxidative activity. A stable and recyclable metal-organic framework Zr-MOF-OH, composed of a binaphthol derivative ligand, has been synthesized and shown to function as an efficient heterogeneous photocatalyst with good catalytic activity and substrate compatibility for the selective oxidation of sulfides to sulfoxides under visible light irradiation. The photocatalytic process involves the conversion of phenolic hydroxyl groups to phenoxyl radicals through excited state intramolecular proton transfer, with triplet O2 directly participating in the reaction, providing wide substrate compatibility and high selectivity.

Summary: Hierarchically ordered porous vinyl-functionalized UIO-66 was utilized to prepare a surface molecular imprinted polymer (MIP-IL@UIO-66) for the rapid and highly selective adsorption of sulfamethoxazole (SMZ) in water. The resulting MIP-IL@UIO-66 showed ultrafast equilibrium rate, large adsorption capability, excellent adsorption selectivity, and good reusability. The adsorption performance of SMZ onto MIP-IL@UIO-66 was superior to that of a commercial solid phase extraction (SPE) adsorbent, with recoveries of 91-106% in water, soil, egg, and pork samples.

Summary: The separation of propane/propylene mixtures is a challenging task in the petrochemical industry. Metal-organic frameworks (MOFs) have been identified as promising materials for this task due to their structural diversity and tunable pore dimensions. However, the low adsorption capacity and slow diffusion kinetics of MOFs have limited their efficiency. In this study, we report the fabrication of nano-sized MOF crystals for propane and propylene separation, which exhibit enhanced adsorption kinetics and improved adsorption capacity compared to micro-sized samples. This represents the highest efficiency among all reported MOF-based splitters for propane/propylene separation.

Summary: CO2 is the main greenhouse gas, and capturing it from flue gas under humid conditions is challenging but important for carbon neutrality. In this study, a highly efficient CO2 capture performance was achieved by integrating specific functionalities such as unsaturated metal sites and amide functional groups. The MOF Fe-dbai exhibited high CO2 adsorption capacity, CO2/N-2 selectivity, and a preserved working capacity under humid conditions. Molecular simulation revealed that the amide CO- group played a crucial role in improving the interaction between Fe UMS and CO2.

Summary: The traditional Haber-Bosch process for ammonia synthesis is energy-intensive and causes nitrate pollution. A sustainable and moderate nitrate electrocatalytic reduction to ammonia (NO3RR) was used to convert waste into a valuable resource. Co3O4 showed the best NO3RR performance among spinel cobalt-based catalysts, and a Co3O4/Co catalyst with a unique nanosheet structure was fabricated. The catalyst exhibited excellent NO3RR properties in a neutral electrolyte and could be used in a continuous flow electrolyzer to significantly increase ammonia production.

Summary: In this study, two isoreticular pillar-layer metal-organic frameworks, Co(aip)(bpy)0.5 and Co(aip)(pyz)0.5, were developed for the separation of C2H4/C2H6. The pore apertures of these frameworks are controlled by changing the length of the pillar ligands. Co(aip)(pyz)0.5, with a shorter pillar ligand, shows reduced pore size and molecular sieving separation of C2H4 from C2H6. Molecular simulation and dynamic breakthrough experiments confirm its high selectivity for C2H4.
