Summary: Iron-based layered double hydroxides (LDHs) have low efficiencies due to electrostatic agglomeration and low electronic conductivity. A MgFeAl LDH/carbonitride (LDH/CN) heterostructure was constructed by triggering the interlayer reaction of citric acid (CA) and urea. The LDH/CN heterostructure achieved nearly 100% bisphenol A (BPA) removal rate in 10 min and exhibited efficient interfacial electron transfer for rapid pollutant degradation. This study provides a rational strategy for forming heterostructure catalysts for environmental cleanup.

Summary: In this study, a low-cost and oxygen vacancies enriched mixed metal oxide derived from red mud-based layered double hydroxide was used as a peroxydisulfate activator to efficiently degrade ciprofloxacin under visible light irradiation. The optimal composite exhibited good performance, with approximately 87.4% degradation of ciprofloxacin achieved within 60 minutes. The oxygen vacancies in the composite were found to improve light absorption and promote electron-hole separation, resulting in the activation of peroxydisulfate and generation of active species for ciprofloxacin degradation.

Summary: A strategy for enhancing the oxygen evolution reaction (OER) catalytic activity of NiFe layered double hydroxide (LDH) by incorporating CoTe nanosheets (NSs) is reported. The hybrid material (CoTe NS/NiFe LDH) exhibits a hierarchical 2D-2D heterostructure with an intact interface between the CoTe NS and NiFe LDH. The presence of CoTe NS on the NiFe LDH enhances charge transfer and reaction kinetics during the OER process, leading to lower overpotentials and excellent stability, outperforming the benchmark RuO2 catalyst.

Summary: Constructing advanced battery-type electrodes with hierarchical core-shell heterostructure is crucial for enhancing the energy density and cycling stability of hybrid supercapacitors. In this study, a hydrangea-like ZnCo2O4/NiCoGa-layered double hydroxide@polypyrrole (ZCO/NCG-LDH@PPy) core-shell heterostructure was successfully synthesized. The ZCO/NCG-LDH@PPy electrode exhibited a high specific capacity of 381.4 mAh g-1 at 1 A g-1 and excellent cycling stability (89.83% capacity retention) after 10,000 cycles at 20 A g-1, owing to the abundant heterointerfaces and synergistic effect among different active components. The ZCO/NCG-LDH@PPy//AC hybrid supercapacitor (HSC) achieved a remarkable energy density of 81.9 Wh kg-1, an outstanding power density of 17,003.7 W kg-1, and superior cycling performance (a capacitance retention of 88.41% and a coulombic efficiency of 93.97%) at the end of the 10,000th cycle. Furthermore, two ZCO/NCG-LDH@PPy//AC HSCs in series could power a LED lamp for 15 min, highlighting its excellent application prospects.

Summary: In this study, ternary layered double hydroxide (LDH) containing Zn, Cu, and Ni was successfully synthesized using hydrolysis route. The synthesized lattice can transform into ZnO containing Cu and Ni upon calcination at a lower temperature of 350 degrees C, and can be reformed back to the layered structure by 'memory effect'. The lattice was used for the formation of polyaniline (PANI)-based composite material. The results indicate the successful incorporation of PANI in the interlayer region, making the ZnCuNi-LDH/PANI composite a potential candidate for various applications in the future.

Summary: Microplastic contamination in marine ecosystems poses a growing concern due to its trophic transfer and negative effects on marine organisms. This study investigates the transfer and impacts of polystyrene microplastics in an estuarine food chain. The results show that microplastics can be transferred through the food chain, although the transfer rates are low. The exposed organisms exhibit stress responses, suggesting the potential risk of microplastics reaching humans through the food chain.

Summary: This study measured the levels of phthalate metabolites in breast milk collected from mothers in southern China. The results showed that phthalates are still prevalent in the region, and breastfeeding contributes to phthalate intake in infants. However, the levels detected do not pose significant health risks to infants based on dietary exposure. The increasing exposure to certain phthalates calls for further research into their sources and potential risks.
