Applications for layered dihydroxides (LDHs) include:

Layered double hydroxides (LDHs) have attracted widespread attention in many research and application fields due to their adjustable composition, layered structure, and rich surface/interlayer chemical properties, mainly reflected in the following aspects:

(1) Electrocatalysis: LDHs, especially transition metal-based LDHs (such as NiFe-LDH and CoFe-LDH), exhibit excellent electrocatalytic properties under alkaline conditions and have been widely studied for oxygen evolution (OER) and overall water electrolysis systems. In seawater electrolysis or impurity-containing electrolysis systems, LDHs have shown potential application value in improving catalytic activity and chlorine corrosion resistance through adjustable metal composition and interlayer structure, and can be used as high-efficiency electrode materials or catalyst precursors in hydrogen energy-related electrochemical systems.

(2) Catalysis and catalytic support: LDHs and their derived layered metal oxides have good structural designability and compositional tunability in multiphase catalytic reactions. Materials represented by NiFe-LDH show good catalytic activity and selectivity in oxidation reactions, hydrogenation reactions, and environmental catalysis, and LDHs can also be used as functional catalytic carriers to achieve fine regulation of reaction paths and active sites by regulating the metal ratio of the laminate and the anions between layers.

(3) Biomedicine and biomaterials: Some LDHs are explored for biomedical directions such as drug delivery, gene transport, and bioimaging due to their good biocompatibility, controllable degradation, and high drug loading capacity. Its interlaminated properties allow it to achieve sustained release of drugs or biomolecules, but its applications are still mainly in the basic research and preclinical research stages.

(4) Cell behavior regulation and biological interface research: LDHs can affect cell adhesion, growth and differentiation through surface chemistry, ion release behavior and nanoscale topology, which has research value in cell behavior regulation and biological interface engineering. Some studies have shown that LDH-based materials can influence stem cell differentiation trends by modulating local microenvironment or ion signals, but this direction is still exploratory research, and the mechanism needs to be further systematically elucidated.

(5) Adsorption and environmental treatment: LDHs have significant anion exchange capacity and large specific surface area, and can be used to adsorb anionic pollutants (such as phosphate, chromate, nitrate, etc.) and some organic pollutants in water, showing good application prospects in water treatment, environmental remediation and resource recovery. In addition, LDHs are renewable adsorbent materials, and their structural reversibility provides the possibility of multiple recycling.
