Summary: Intercalation of carboxylate into layered zinc hydroxides can be achieved directly at room temperature, resulting in crystalline, soluble, and functionalized materials. This direct synthesis method leads to high yields of exfoliated monolayer nanosheets, with high solubilities in alcohols and water. By altering the carboxylate ligand, functional groups suitable for post-synthetic modification or for detection by fluorescence are also introduced.

Summary: The NiO/NiGa2O4 heterojunction-based material synthesized from atomically mixed Ni-Ga precursors of layered double hydroxides (LDH) shows high response to toluene at a low temperature of 200 degrees C. Compared to the coprecipitation method prepared analogue, the LDH prepared material exhibits higher response and selectivity, along with long-term stability. X-ray diffraction, X-ray photoelectron spectroscopy and ultraviolet photoelectron spectroscopy confirm the efficient fabrication of NiO/NiGa2O4 heterojunctions promising for high performance gas sensors.

Summary: The exfoliation ability of nitrate based Mg-Al LDH into single or multilayer nanosheets is strongly influenced by nitrate anion orientation and layer charge. Superior exfoliation was observed for nitrate LDH compared to clays with carbonate, sulfate, chloride, or iodide as charge balancing anions, with an optimum composition for single nanosheet exfoliation at x≈0.25. The study also found that particles with platelet-like morphology exfoliated more effectively, suggesting that hydrothermal treatment may enhance exfoliation yields.

Summary: This review summarizes and compares recent advances in effective and facile strategies for the rational design of transition-metal-based layered double hydroxides (TM-LDHs) nanosheets as electrocatalysts, including increasing the number of active sites, improving the utilization of active sites (atomic-scale catalysts), modulating the electron configurations, and controlling the lattice facets. The utilization of these fabricated TM-LDHs nanosheets in various applications, such as oxygen evolution reaction, hydrogen evolution reaction, urea oxidation reaction, nitrogen reduction reaction, small molecule oxidations, and biomass derivatives upgrading, is discussed by systematically analyzing the corresponding fundamental design principles and reaction mechanisms. Furthermore, the existing challenges in increasing the density of catalytically active sites and the future prospects of TM-LDHs nanosheets-based electrocatalysts in each application are addressed.

Summary: Sonodynamic therapy (SDT) has shown promise as a cancer treatment, and researchers have developed ultrathin nanosheets as highly efficient sonosensitizers for SDT. The nanosheets undergo a phase transformation from polycrystalline to amorphous, resulting in higher reactive oxygen species (ROS) generation activity under ultrasound (US) irradiation. The enhanced performance of the nanosheets can be attributed to defect generation and electronic structure changes caused by the phase transformation. With polyethylene glycol modification, the nanosheets can effectively induce cell death in vitro and tumor eradication in vivo under US irradiation.

Summary: This study reports a method of forming a crystalline-amorphous (c-a) interface by modulating the crystallinity of the material to improve the catalytic activity and structural stability of oxygen evolution reaction (OER). By adjusting the cobalt content in NiFe layered double hydroxide (LDH), the c-a interfacial site of the material can be controlled, resulting in low overpotential and excellent stability.

Summary: A novel method for preparing high-entropy oxides (HEO) using multivariate composition layered double hydroxides (LDHs) as precursor was successfully developed. Thermal treatment at temperatures above 600 degrees C resulted in the complete transformation of LDHs into single spinel phase HEOs. The HEO-600 catalyst exhibited impressive activity and stability in the catalytic oxidation of toluene, attributed to the abundance of surface oxygen vacancies and variable metal valence. This work presents a simple way to obtain HEO materials and provides technical support for the application of HEO catalysts in VOCs removal.

Summary: Layered double hydroxides (LDHs) with 2D structures show great potential in electrocatalysis due to their ease of preparation and structural flexibility, but their application is limited by stacking structures and low activity. Strategies are being developed to adjust their morphological and electronic structure to enhance their performance in catalysis.

Summary: In this study, a Cl--intercalated CoFe layered double hydroxides (CoFe-Cl-LDH/CNT) composite was successfully synthesized and demonstrated as a novel high-performance anode for ACIBs in a neutral NaCl aqueous solution. The material showed a high initial capacity and good cycling stability, attributed to the reversible intercalation/deintercalation of Cl- ions and the valence changes of Co2+/Co3+ and Fe2+/Fe3+. Furthermore, the hybridization with CNTs improved the electronic conductivity. This research provides a new opportunity for the future development of ACIBs or aqueous desalination technology.
