Summary: This paper describes the preparation and study of new bifunctional samples (Y(0.9)Ln(0.1)VO(4)/Fe3O4)@SiO2 and [(Y(0.9)Ln(0.1)VO(4)@SiO2)/ Fe3O4@SiO2] with Ln = Nd or Tb. The influence of Fe3O4 content and silica coating on the Y(0.9)Ln(0.1)VO(4)@SiO2 samples is analyzed, and their potential utility is determined. These samples, which have potential applications in biomedicine, can be directed using an external magnetic field and allow the visualization of diseased cells. The experimental and theoretical studies provide insights into the structural and vibrational properties of the samples, confirming the presence of silica coating. The [(Y(0.9)Ln(0.1)VO(4)@SiO2)/Fe3O4@SiO2] samples show the most suitable properties for use as bifunctional materials.

Summary: This research developed two novel electromagnetic nanocomposites, Fe3O4@void@SiO(2)nanochains and Fe3O4@void@SiO2@PPy nanochains, and found that Fe3O4@void@SiO2@PPy nanochains have stronger absorption capability and broader effective absorption bandwidth than Fe3O4@void@SiO(2)nanochains due to the introduction of polypyrrole shells. With a minimum reflection loss value of -54.2 dB and a maximum effective absorption bandwidth of 5.90 GHz, Fe3O4@void@SiO2@PPy nanochains are promising microwave absorption candidates.

Summary: In this study, phosphate-functionalized Co3O4/kaolinite (P-Co3O4/Kaol) catalysts were prepared and used for the degradation of environmental pollutants using peroxymonosulfate (PMS). The presence of phosphate enhanced the adsorption of PMS and the electron transfer of Co2+/Co3+ cycles, resulting in superior catalytic performance and stability of P-Co3O4/Kaol. Additionally, the ·OH radical was identified as the dominant reactive species for the degradation of Orange II. This work provides a novel preparation strategy for functionalized nanoclay-based catalysts for effective pollutant degradation.

Summary: In order to achieve a high separation efficiency of photogenerated carriers in semiconductors, constructing high-quality heterogeneous interfaces as charge flow highways is critical and challenging. This study successfully demonstrates a new strategy for constructing high-quality heterogeneous interfaces by consciously modulating interfacial chemical bonds and internal electric fields (IEFs) in a 0D/0D/1D-Co3O4/TiO2/sepiolite composite catalyst. The results show that the interfacial Co2+-O-Ti bond plays a major role as an atomic-level charge transport channel at the p-n junction, and increasing the Co2+/Co3+ ratio enhances the IEF intensity, thereby enhancing the photoelectron separation and migration efficiency. The study also shows the efficient synergy between photocatalysis and peroxymonosulfate activation for deep pollutant degradation and reduced ecotoxicity.

Summary: The structure and energetic evolution of HNTs are important for the acid-leaching process. Molecular dynamics simulation was used to study the specific surface area, pore volume, and bond distribution of HNTs at different Al leaching percentages. Increasing the Al leaching percentage leads to gradual enlargement of the inner diameter of HNTs and the formation of nanoporous interlayer spaces. The interlayer nanopores greatly increase the specific surface area and pore volume of HNTs, especially after 50% Al leaching. The presence of water molecules also affects the thermodynamics and structure evolution of HNTs. Although transition structures with high loading capacity may not be naturally stable, they can be stabilized or achieved through fast transient regulation methods.

Summary: We synthesized heterojunction structures of Co9S8/Ni3S2 nanowire arrays and amorphous goethite particles as efficient and stable bifunctional electrocatalysts for electrochemical overall water splitting. The interfacial charge inhomogeneity caused by the heterojunction contact generates a built-in electric field, favoring the hydrogen/oxygen evolution reactions. FeOOH/Co9S8/Ni3S2 exhibits impressive catalytic activity for the oxygen evolution reaction, achieving a large current density at low overpotential, and shows excellent stability for 1440 hours. Furthermore, the bifunctional FeOOH/Co9S8/Ni3S2 catalysts achieve an excellent OWS output.

Summary: Sodium metal has great potential as a cheap anode for rechargeable batteries, but the growth of sodium dendrites has been a problem. This study presents an effective strategy to prevent diffusion and achieve uniform sodium deposition using a coating of anion-anchoring halloysite nanotubes (HNTs). The HNTs were activated with acid to expose active sites that effectively interact with the SO3CF3- anion, promoting the dissociation of sodium salts and allowing for steady sodium deposition, high Coulombic efficiency, and long cycle life. This work provides theoretical basis for the design of nanoclay for dendritic-free metal batteries with abundant and effective active sites for fixing anions.
