Summary: In this study, a ZnO/Pd@ZIF-7 core-shell structure-based gas sensor was fabricated using a self-sacrificial method, which significantly improved the sensing selectivity of methane by utilizing the ZIF-7 filter. At low temperatures, ZIF-7 enriched gases and enhanced the response of methane, carbon monoxide, and ammonia. At elevated temperatures, ZIF-7 separated gases based on their molecular polarity, hindering the diffusion of polar carbon monoxide and ammonia more than nonpolar methane. This study not only provides a possible solution for enhancing the selectivity of metal oxide semiconductor (MOS) sensors to methane but also inspires the development of highly selective gas sensors.

Summary: In this study, NCNT/ZIF-8 nanocomposite was prepared via the hydrothermal method for providing clean fuels through desulfurization. The nanocomposite showed excellent adsorption capacity for DBT, attributed to the synergistic effects of NCNT and ZIF-8, the presence of basic groups in NCNT structure, and high surface area and pore volume. The regenerated NCNT/ZIF-8 maintained good performance even after 3 adsorption-desorption cycles with almost unchanged adsorption capacity.

Summary: Zeolitic imidazolate framework-8 was synthesized in a containerless state using acoustic levitation, which affected the coordination connection of ligands and resulted in different particle size distribution compared to normal conditions. The influence of droplet evaporation during acoustic levitation synthesis was investigated using methanol as the solvent. Surface evaporation caused deformation, vibration, and shape oscillation of the droplets, leading to a decrease in particle size distribution.

Summary: In this study, novel nano-sized FOX-7/ZIF-8 composites were constructed using a facile liquid-assisted mechanochemical reaction. Unlike the two-step thermal decomposition of raw FOX-7, the prepared FOX-7/ZIF-8 composites exhibited a single high-intensity exothermal decomposition attributed to the catalytic effect of ZIF-8. The mechanical sensitivity of FOX-7/ZIF-8 composites was reduced due to the nano-sized energetic materials and the buffering effect of ZIF-8.

Summary: In this study, a porous ZIF-11@ZIF-8 core-shell composite structure metal-organic framework (MOF) was successfully synthesized using the solvent-assisted linker exchange (SALE) technique. The ZIF-11 acts as the core and enhances the adsorption capacity, while the ZIF-8 provides improved adsorption selectivity. Characterization analyses confirmed the formation of the core-shell structure, and the synthesized MOF exhibited high surface area and micropore volume. The adsorption capacity of CO2 and the adsorption selectivity of CO2/N2 and CO2/CH4 were significantly increased.

Summary: The current performance of Li-, Na-, or K-ion batteries is mainly limited by the specific capacity of the positive electrode. It is crucial to achieve the highest capacity possible for a given electrode material. In this study, the performance limitation of KVPO4F, a potential material for K-ion batteries, is investigated. The capacity limitation of KVPO4F is found to be related to a kinetic competition between K+ deinsertion and side reactions caused by electrolyte degradation at high potentials.

Summary: In this study, we have successfully created a new aryl amino-substituted graphitic carbon nitride (g-C3N4) catalyst with atomically dispersed Mn that is capable of directly generating hydrogen peroxide (H2O2) from seawater. This catalyst showed excellent reactivity, achieving up to 2230 μM H2O2 in 7 hours from alkaline water and up to 1800 μM from seawater under the same conditions. The catalyst can be easily recovered and reused without any significant loss in performance. The generation of H2O2 in this catalyst occurred through a unique two-electron water oxidation reaction process involving both direct and indirect pathways.
