Summary: The study achieved rapid and selective removal of Cs+, Sr2+, and Eu3+ ions using two metal sulfides with distinct structures and arrangements of mixed cations. It is the first time that ionic liquid cations and protonated organic amines have been simultaneously incorporated into metal sulfides, showing high removal efficiency and selectivity. The research highlights the potential of metal sulfide ion exchangers for radionuclide remediation, challenging the consensus about the exchangeability of large-sized organic cations.

Summary: The effects of synthesis conditions on the structure of tetrathiotungstate intercalated NiAl layered double hydroxides were investigated. It was found that the crystallinity of the final product depends on the initial pH value and exchange temperature, while the interlayer distance is mainly affected by the exchange temperature and drying temperature.

Summary: This study aimed to extract orthophosphate (ortho-P) from lipid-rich waste AF liquor (AFL) by Mg/Al layered double hydroxides (Mg/Al LDHs) adsorption. Low carbonate level was found to be favorable for P extraction. Kinetics and mechanisms analysis indicated that the adsorption of P onto Mg/Al LDHs was a rapid physiochemical process.

Summary: Layered double hydroxides (LDHs) are investigated as anode materials for potassium ion batteries (PIBs), with MgFe-LDH showing higher K+ storage capacity but lower initial Coulombic efficiency compared to MgAl-LDH. The dominant mechanisms for K+ storage in these materials are electrical double layer effect and a faradaic process involving a conversion reaction between Fe3+ and Fe2+. The study suggests the potential of developing LDHs as efficient anode materials for PIBs.

Summary: The study found that P-LDHs at lower concentrations slightly delayed seed germination, but at appropriate levels, they promoted plant growth and increased yield. Different concentrations of P-LDHs had varying effects on lettuce growth, with 1.0% concentration showing the most beneficial results.

Summary: This study presents supported Pt catalysts using layered double hydroxides (LDHs) as supports, which exhibit highly dispersed Pt nanoparticles, water resisting property, and strong interaction of Pt with LDHs. Compared to traditional Pt/C, these catalysts show excellent anti-aggregation performance and catalytic activity at high temperature and humidity conditions. Density Functional Theory calculations reveal the strong interaction between Pt nanoclusters and hydrogen defective LDHs surface, along with significant interfacial charge transfer and metal electronic structure modification, which can inhibit Pt aggregation on LDHs and enhance catalytic activity. These findings deepen the understanding of the effects of metal-support interactions in the LPCE process and provide valuable insights for the design and preparation of highly efficient hydrophobic catalysts on LDHs with potential applications in water detritiation.

Summary: The chloride-ion battery (CIB) based on anion transfer is important for developing new battery technologies. Layered double hydroxide (LDHs), as a rare anion intercalated layered material, has attracted attention as promising cathodes for CIBs. However, developing a general methodology to effectively design and assess the usability of unexploited LDHs for CIBs is still challenging due to the compositional diversity.
