Summary: The development of new adsorbent materials for removing toxic ions from water is an important research direction. In this study, Zr-based metal-organic framework hierarchical porous nanofibre membranes (MOFs@PIM-W) were successfully synthesized and investigated for their adsorption properties and mechanism for fluoride ions in water. The formation of Zr-F bonds in Zr-based MOFs was found to be the primary reason for the rapid, effective, and stable removal of fluoride ions from water. Moreover, the hierarchical porous nanofibre membranes achieved a higher removal rate of fluoride ions compared to common powder adsorbents and the conventional static adsorption process, attributed to their hierarchical porous structures. By modifying the types of MOFs, the obtained nanofibre membranes also demonstrated efficient removal of Hg(II) ions from water under a wide range of pH environments (pH = 2-10), with a removal rate of up to 99%.

Summary: Worldwide rapid urbanization and development have led to the release and dispersion of anthropogenic heavy metals, posing serious threats to aquatic ecosystems and human health. Although various methods for removing heavy metal ions from aqueous solutions have been explored, there is still a need for improvement in the efficient and pertinent treatment of heavy metal pollution. Adsorption is considered the best technique for heavy metal removal, and metal-organic frameworks (MOFs) are recognized as one of the most promising emerging adsorbents with excellent adsorption properties. This review provides a comprehensive overview of MOFs synthesis techniques, functionalization methods, and adsorption mechanisms, as well as a detailed comparison of their applications in heavy metal removal, aiming to offer a strong reference for MOFs synthesis and a feasible solution for heavy metal treatment.

Summary: This study reviews the synthesis of metal-organic framework (MOF) materials and their application in removing fluoride from contaminated water. The study compares the adsorption mechanisms and characteristics of different MOFs, such as initial fluoride concentration, adsorbent dosage, solution pH, contact time, adsorption capacity, thermodynamic and regeneration studies. The hydrothermal/solvothermal synthesis method is commonly used for MOF preparation, and MOFs based on aluminum metal ions show higher surface areas. The main fluoride adsorption mechanisms are electrostatic attraction and/or complexation. Several materials are effective over a wide pH range. Most MOFs can be successfully regenerated for four to six cycles, with the sorption process being endothermic in most cases.

Summary: One of the challenges in multicomponent metal-organic frameworks (MOFs) is to achieve selective product formation by finely tuning their active centers. In this study, a technique called cluster labilization was used to create hierarchically porous MOF composites with hollow structures and adjustable active centers. By partially replacing zirconium with cerium in the hexanuclear clusters of UiO-66, unevenly distributed yolk-shell structures (YSS) were formed, which can be further transformed into single-shell hollow structures (SSHS) or double-shell hollow structures (DSHS) through acid treatment or annealing. These structures exhibit tunable catalytic activity, reversed selectivity, and high stability in tandem reactions and photoreactions.

Summary: Detecting precursor chemicals is of great importance for sniping drugs from the source. In this study, the semiconductor gas sensor array is used to measure precursor chemicals and interference samples under dynamic and static measurement. Qualitative and quantitative analyses are conducted using the principal component analysis, support vector machine, and K-nearest neighbor algorithms. The qualitative results show that the SVM and KNN algorithms perform well in the two measurement methods. For quantitative analysis, support vector regression is utilized, and the mean absolute error is smaller in the dynamic measurement than in the static measurement. Stability experiments conducted after a month reveal that the qualitative recognition in dynamic measurement is better than in static measurement, indicating the advantages of dynamic measurement for real-time detection of precursor chemicals.

Summary: In this study, the electron polar transport properties of two-dimensional heterojunction material were discovered and utilized to greatly improve the selectivity of butanone sensors. By synthesizing ultra-thin porous ZnO nanosheets modified with SnO2/NiO heterogenous particles, a detection limit of 20 ppb for butanone was achieved with a response of 328 to 100 ppm butanone, the lowest known detection limit. The synergistic catalytic effect of SnO2/NiO heterogenous particles was revealed to contribute to the high response and low detection limit of butanone. The possible mechanism for the generation of electron polar transport phenomenon in two-dimensional heterojunction material was analyzed. This work provides a novel perspective for achieving both selectivity and detection limits in gas sensors, with universal applicability and application potential.

Summary: The Wolkenstein model has been the main mechanism for semiconductor sensing of oxygen adsorption and desorption since it was proposed in the 1990s. However, metal oxide-based sensors targeting ammonia face difficulty in achieving sub-ppm detection limits, high selectivity, high response, and room temperature operation under the oxygen adsorption desorption mechanism. To address this, a CO2-catalyzed intermediate adsorption-based sensing mechanism was proposed, utilizing CO2 instead of oxygen to achieve adsorption-desorption equilibrium. C-SnO2 plays a reductive role in the response process, resulting in high selectivity, anti-interference, and low detection limits for ammonia gas at room temperature.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
