Summary: In this study, CuAl layered double hydroxide (LDH) and polymeric carbon nitride (g-C3N4, GCNN) were assembled into novel 2D/2D CuAl-LDH/GCNN heterostructures for visible-light-driven water splitting. The heterostructures exhibited significantly enhanced H-2 evolution, with the optimal LDH loading of 0.2CuAl-LDH/GCNN showing a 32-fold increase compared to GCNN. Additionally, 0.2CuAl-LDH/GCNN generated 1.5 times more O-2 than GCNN. The improved photocatalytic performance was attributed to efficient charge separation at the heterojunction interface, enhanced utilization of longer-wavelength photons, and higher surface area for catalytic reactions.

Summary: A novel hybrid composite consisting of biochar, layered double hydroxide, and chitosan was successfully synthesized and used for adsorptive removal of Eriochrome black T from water. The composite exhibited a heterogeneous structure with abundant surface functionalities, which facilitated faster and enhanced removal of the dye. The kinetic and equilibrium adsorption data showed good fitting to the pseudo-second order model and Langmuir and Redlich Peterson isotherm models, respectively. The spectroscopic analysis and experimental results suggested that the adsorption process was mainly governed by electrostatic, chemical, and anion-exchange interactions. This study highlights the importance of coupling composite materials with bio-fillers for efficient purification of dye-contaminated water streams.

Summary: This study reported the development of a series of new organically functionalized layered double hydroxide (LDH) adsorbents for the removal of per- and polyfluoroalkyl substances (PFAS) from contaminated water, with a specific focus on perfluorooctanoic acid (PFOA). The organically functionalized LDHs showed efficient PFOA adsorption by combining strong electrostatic and hydrophobic interactions. The adsorption kinetics and capacities were found to be higher for the organically functionalized LDHs compared to the unmodified LDH. Additionally, the organically functionalized LDHs exhibited improved performance under various water chemistry conditions and remained effective after repeated adsorption-regeneration cycles. This work suggests that organically functionalized LDHs hold great promise for the treatment of PFAS-contaminated water.

Summary: This study investigated the performance of two types of LDH materials for the removal of PFAS, finding that Zn-Al LDH showed higher efficiency and better adsorption capacity for PFOA compared to Mg-Al LDH. The presence of natural organic matter had minimal impact on PFOA removal by Zn-Al LDH, while sulfate severely inhibited PFOA adsorption, suggesting that electrostatic interactions may play a primary role in the adsorption mechanism onto LDHs for PFAS removal.

Summary: Hollow Prussian blue analog@defect-rich layered double hydroxide S-scheme heterojunctions were successfully synthesized using two-step etching strategies. The hollow core-shell structure provided more active sites, and in-situ XPS and work function analysis confirmed the formation of S-scheme heterojunctions. Transient photoluminescence and photoelectrochemical tests demonstrated longer charge lifetimes and enhanced photoelectrochemical properties. The presence of photothermal effect increased the reaction temperature and promoted the photocatalytic process. This research presents a new idea for the design of S-scheme photocatalysts.
