Summary: The sandwich-like MXene/graphene oxide/nickel-manganese layered double hydroxide (MGL) with more exposed active sites is efficiently assembled by the conductive interface of MXene, graphene oxide (GO) and intercalated layered double hydroxide (LDH). The unique nanostructure prevents MXene stacking problem and promotes the specific capacity of LDH. GO covers the compound surface to accelerate charge transfer and increase electron density, while stable carbon materials contribute to the excellent specific capacity and cycle stability of MGL as cathode material.

Summary: In this study, a self-disinfecting fabric decorated with nickel-chromium-iron layered double hydroxide (NiCrFe-LDH) was successfully fabricated for visible-light-driven photocatalytic sterilization. The NiCrFe-LDH/WCF showed excellent inactivation of bacteria and degradation efficiency for antibiotics, with improved photocatalysis compared to NiCr-LDH/WCF. The enhanced photocatalytic performance was attributed to the partial substitution of Fe3+ in the NiCr-LDH, which enhanced light adsorption capacity and improved the separation efficiency of photogenerated carriers. This visible light responsive fabric holds great potential for environmental microbial inactivation and treatment of organic contaminants in water, as well as for the production of new generation textiles in the medical care industry.

Summary: Photocatalysis is a green technology used to drive chemical reactions under mild conditions, providing solutions to global energy and environmental issues. Layered double hydroxides (LDHs) have gained attention in photocatalysis due to their easy synthesis, low cost, and tunability. Recent research focuses on improving the performance of LDH-based photocatalysts through design strategies for high-performance solar fuel generation.

Summary: The magnetite CuFe-layered double hydroxide (LDH) nanocomposite was synthesized and used to activate persulfate (Ps) under visible light. The target pollutant, Rhodamine 6G (Rh6G), was effectively degraded and removed under optimal conditions. The study also investigated the effects of anions in water sources, identified the contribution of oxidant species, proposed a degradation pathway, and evaluated energy consumption and cost. These findings contribute to the improvement of dyestuff wastewater treatment.

Summary: In this study, magnesium/aluminum-layered double hydroxide (MgAl-LDH) and bentonite (BT) nanocomposites (LDH-BT) were prepared using different methods and their chromate adsorption performance was investigated. The results showed that the LDH-BT composites prepared by solid-phase hybridization exhibited high chromate removal efficiency, with a positive relationship between the LDH ratio and chromate removal efficiency. It was confirmed that LDH-BT is a practical nanocomposite for soil and groundwater remediation.

Summary: This study highlights the enhancement of controlled release behavior of quinclorac (QC) by incorporating carboxymethyl cellulose (CMC) into zinc/aluminium layered double hydroxide (Zn/Al-LDH). The Zn/Al-LDH-QC-CMC nanocomposites showed improved performance in releasing QC, with prolonged release time, indicating their potential in mitigating the negative effects of excessive herbicide usage in paddy cultivation. The kinetic study revealed that the release mechanism of Zn/Al-LDH-QC-CMC follows pseudo-second order kinetics, involving dissolution of the CMC matrix and ion exchange process.

Summary: Ultrathin NiAl-layered double hydroxides (U-LDHs) nanosheets with a thickness of 3-8 nm, wide pore size distribution, and high specific surface area were synthesized using a urea-assisted strategy. U-LDHs nanosheets exhibited significantly higher photocatalytic activity for methylene blue degradation compared to bulk NiAl-LDHs (B-LDHs). The superior performance of U-LDHs was attributed to their efficient separation and transfer of photogenerated carriers, as well as the ability to adsorb oxygen and generate superoxide radicals.
