Summary: Cu-based metal organic frameworks (MOFs) have potential as adsorbents for selective adsorption desulfurization (SADS) of mercaptans in fossil fuels, but the problem of structural collapse hinders their application due to strong interaction between copper cations and mercaptans. to find a solution, the factors influencing the SADS ability of MOFs are thoroughly discussed by comparing 16 MOFs. The study reveals that the binding strength between copper cations and mercaptan is mainly determined by the coordination environment of the copper cations. one MOF, ADODAA, with copper cations coordinated with two oxygen and two nitrogen atoms, demonstrates significantly higher stability and renewability compared to other Cu-based MOFs, as a result of its moderate binding strength towards mercaptan. This work unravels the strong dependence of MOFs stability on the coordination environment of its metal cations and provides a platform for constructing highly stable SADS adsorbents.

Summary: The introduction of ion-imprinted polymers (IIPs) based on the molecular imprinting methodology has provided an innovative solution for the selective recognition of heavy metal ions (HMIs). Recent advances have demonstrated that IIPs exhibit higher selectivity coefficients, enabling various environmental applications such as extraction, monitoring, detection, and quantification of HMIs. This review critically analyzes relevant literature studies from the past decade, focusing on the selective removal of transition metal ions using IIPs. It discusses the chemical components, ion-imprinting technologies, characterization methods, synthesis parameters, adsorption performance, and solid phase extraction of heavy metal ions by different IIPs.

Summary: Fe3O4-Ti3C2Tx (FeMX) adsorbent with different doping amounts of Fe3O4 was prepared by one-step hydrothermal method to improve the chemical stability and ion adsorption capacity of Ti3C2Tx. The maximum theoretical Pb(II) adsorption capacity of FeMX adsorbent was found to be 210.54 mg/g. The adsorption mechanism revealed that Fe3O4 nanoparticles were evenly dispersed and intercalated between Ti3C2Tx nanosheets, enhancing the specific surface area and layer spacing of Ti3C2Tx nanosheets and improving the ability to remove Pb(II). This study provides a promising route for developing MXene matrix composites with excellent heavy metal ion adsorption properties.

Summary: Synthetic NaX zeolite exhibited selective adsorption capacity towards heavy metal ions, with Pb2+ and Cu2+ showing higher affinity due to their higher electronegativity, impacting the stability of the framework. The negatively charged O in the Si-O-Al structure of NaX zeolite played a key role in the selective adsorption mechanism for high electronegative metal ions, resulting in a strong affinity. This study evaluates the potential application and efficiency of zeolite in separating and recovering specific metal ions from industrial wastewater.

Summary: Heavy metal ions, a major pollutant, can cause serious health problems. Ion-exchange resin beads were used as supports for magnetite synthesis to produce heavy metal adsorbents that can be separated by magnetic field. The preparation involved ion replacement and particle formation, resulting in relatively large magnetite crystal particles. Adsorption experiments confirmed the ion-exchange effect of the magnetic adsorbent.

Summary: In this study, we developed a green synthetic strategy to obtain a polythiophene (PTh)/MnO2 composite with high selectivity for heavy metal adsorption. By adjusting the core-shell structure and core MnO2, the composite exhibited efficient adsorption of heavy metal ions. Through experiments and calculations, it was found that this selectivity was due to the synergetic self-doping nature between PTh and MnO2, allowing for robust recycling of the composite in the environment.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

Summary: This research developed an effective approach to enhance the charging rates of lithium ion batteries (LIBs) by strategically incorporating carbon nanotube (CNT) conductivity boosters into Li4Ti5O12 (LTO) electrodes. Multi-layer architectures comprising CNT-rich and CNT-free LTO electrode layers were manufactured using a layer-by-layer spray coating method to promote charge transfer kinetics of high mass loading electrodes. The best performing multi-layer was paired with a spray-coated LiFePO4 (LFP) positive electrode, resulting in attractive power performance that outperformed conventional LTO || LFP combinations.

Summary: This study investigates the relationship between the morphology of PMMA monopolymers and PMMA-PHEMA copolymers with the expected nature of surfactant-free microemulsions (SFMEs) before polymerization. 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.
