Summary: A cyclometalated ruthenium complex (1) with 2-phenylbenzimidazole as the ligand was synthesized and used as a colorimetric chemosensor to detect Hg2+ and Cu2+. The presence of Hg2+ caused a blueshifted absorption and a solution color change from red to yellow, while the addition of Cu2+ resulted in an attenuated absorption and a color change from red to colorless. The detection limits were calculated to be 0.25 μM for Hg2+ and 0.45 μM for Cu2+. Moreover, complex 1 was used to recognize Hg2+ and Cu2+ in dyed paper strips and spiked water samples, respectively.

Summary: The role of functional groups in the adsorption process of functionalized layered double hydroxide (LDH) to target pollutants was investigated. Functionalized NiFe-LDH with 2 mercaptoethane sulfonic acid (MS) as an intercalation modifier was prepared. Molecular dynamics simulation revealed the interfacial interaction between the functional groups and the NiFe-LDH surface. The results showed that the sulfonic acid group self-assembled electrostatically with the LDH laminate, while the sulfhydryl group complexed heavy metal ions. The adsorption experiments demonstrated significantly improved adsorption performance of the modified NiFe-LDH for Cd2+, Mn2+, and Co2+ ions. The molecular dynamics simulation and wavefunction analysis provided insights into the mechanism of enhanced adsorption capacity by the functional groups.

Summary: This paper introduces a novel Li-O2 battery electrocatalyst, a surface-functionalized CoP/Ti3C2Tx composite. The composite exhibits optimized electronic structure and active electrons, which enhance the efficiency of electrochemical reactions. The accordion shaped Ti3C2Tx with large specific surface area and excellent electronic conductivity enables sufficient exposure of active sites and Li2O2 deposition. Transition metal phosphides provide more active catalytic sites and exhibit good electrocatalytic performance. As an electrocatalyst in Li-O2 battery, the CoP/Ti3C2Tx composite achieves high specific discharge capacity and low overpotential, outperforming CoP and Ti3C2Tx individually. The application of transition metal phosphides and MXene in Li-O2 battery not only demonstrates higher cycling stability of the prepared composite, but also points out the direction for improving their electrochemical performance.

Summary: The use of DESs as replacements for traditional solvents in the recovery process of lithium-ion batteries has been widely reported. This study proposes a DES modified by reducing agents, which overcomes the challenges faced by previous research, such as high viscosity, poor reuse performance, and operation conditions. The DES of GUC and LAC with 1 wt% ascorbic acid can dissolve nearly 100% of LCO and NCMs under mild conditions. After stripping Co and supplementing VC, the modified DES can maintain its dissolution properties for at least three cycles. The acidity and reducibility of the DES were also measured as key factors for the dissolution of Li and Co.

Summary: In this study, Fe2O3/CNFs composites were prepared by the in-situ transformation method, combining carbon nanofibers (CNFs) with hollow rice-grained alpha-Fe2O3 nanoparticles. The rational microstructure design reduced the filling ratio, optimized impedance matching, and improved electromagnetic wave absorption performance. The Fe2O3/CNFs composites achieved strong reflection loss (-38.1 dB) and broad effective absorption bandwidth (4.6 GHz) at a low filling ratio (20 wt.%), and analysis of electromagnetic parameters confirmed the crucial role of the microstructure in the performance improvement. With optimized impedance matching and a simple preparation method, Fe2O3/CNFs have broad application prospects in electromagnetic wave absorption.

Summary: MXenes, as typical two-dimensional layered structure materials, have been widely used in energy conversion and storage due to their high conductivity, ion transport ability, and rich surface structures. Recently, MXenes and their composites have been widely employed in secondary batteries, especially sodium-ion batteries (SIBs), with obvious performance improvement. By utilizing the advantages of MXenes, the construction of surface-functionalized MXenes and MXene-based composites effectively improves the conductivity and mass-transport properties of composites, alleviates volume expansion, and enhances the capacity properties, rate performances, and cycle stability of SIBs.

Summary: Through regulating the synthesis process, ZnCo2O4 with a unique Co site was obtained by replacing Co2+ and Co3+ sites in Co3O4 with Zn and Al atoms. The Li-O-2 batteries based on ZnCo2O4 showed longer cycle life than that of CoAl2O4, suggesting that Co-Oh(3+) site is a relatively better geometric configuration than Co-Td(2+) site for Li-O-2 batteries.

Summary: In this study, the extraction effect and complexation mechanism of C2-POPhen and C4-POPhen with the high-valence actinides U(VI) and Th(IV) were systematically investigated. It was found that the POPhen extractants exhibited excellent coordination and extraction ability for U(VI) and Th(IV) under highly acidic nitrate conditions. C4-POPhen showed stronger extraction capacity compared to C2-POPhen, and both ligands had a stronger extraction capacity for Th(IV) than U(VI) under the same experimental conditions. The study also revealed the formation of 1:1 and 1:2 metal-to-ligand complexes between POPhen extractants and Th(IV) through slope analysis and spectroscopic studies, and the structures of these complexes were elucidated by X-ray crystallography. This study provides valuable insights into the extraction effect and complexation mechanism of POPhen extractants with high-valence actinide elements and serves as a basis for the development of advanced actinide separation processes.
