2022年9月1日 · In this study, the porous LiAl-LDHs are converted into the crosslinked sodium alginate hydrogel to prepare LiAl-LDHs adsorbent beads. The surfactants act as soft templates and the LiAl-LDHs nanosheets are packed with a morphology of large mesoporous structure and high specific surface area.

2019年9月6日 · Here, we examine this transformation in partially deuterated LiOH solutions, using multinuclear, magic angle spinning, and high field nuclear magnetic resonance spectroscopy (27 Al and 6 Li MAS NMR), with supporting X-ray diffraction and scanning electron microscopy.

2023年9月15日 · Herein, an interlayer anion regulation strategy was proposed to endow LiAl-LDHs with superior resistance to deactivation induced by excessive Li + deintercalation through strengthening the interlayer interactions.

2013年2月1日 · This study demonstrated the feasibility of a one-step process for the synthesis of Li/Al LDH using LiOH and Al metal. The formation of Li/Al LDH is determined by the Al/Li molar ratio, the LiOH solubility and the water content in the system. Pure Li/Al LDH precipitate was obtained in the range of 0.1 ≤ Al/Li ≤ 2.

2023年8月19日 · Lithium-aluminum layered double hydroxides (LiAl-LDH) have been be successfully applied in commercial-scale for lithium extraction from salt lake brine, however, further advancement of their applications is hampered by suboptimal Li+ adsorption performance and ambiguous extraction process.

2019年9月16日 · Here, we examine this transformation in partially deuterated LiOH solutions, using multinuclear, magic angle spinning, and high field nuclear magnetic resonance spectroscopy (27 Al and 6 Li MAS NMR), with supporting X-ray …

2012年8月10日 · The results indicated that the Li–Al LDHs can be effectively used to remove fluoride from water, where the maximum percentage removal (97.36%) could be reached and the adsorption equilibrium could be attained within 1 h.

A layered double hydroxide (LDH) with chemical composition LiAl(OH) ·2HO was prepared a wet chemical route of gel to crystallite (G–C) conversion at 80 °C involving the reaction of hydrated alumina gel, AlO ·HO (80<<120) with LiOH (LiO/AlO ≥0.5) in presence of hydrophilic solvents such as ethanol under refluxing c

2001年10月30日 · Layered double hydroxides (LDHs) with a cation composition of LiAl 2 have a wide range of potential applications as catalysts, catalyst supports, and precursors for refractory oxide materials, including several industrially important lithium aluminate phases.

2025年3月15日 · We demonstrated Fe 3+ could effectively incorporate and form the binder-free LiAlFe-LDH@NiAl-F adsorbent with enhanced lithium adsorption capacity from the microgram level to 5.2 mg/g and stability of over 30 adsorption-desorption cycles.
