Recent advances in the design and surface modification of titanium-based LDH for photocatalytic applications

Modulating chelation with pH sensitivity for controlled structural defects and enhanced electrochemical and photocatalytic activities of LDH films

“…Layered double hydroxides (LDHs), versatile and environmentally friendly materials, have gained significant attention in research and applications, owing to their multifunctional properties, which encompass their effectiveness as photocatalysts and their utility as corrosion-resistant coatings for valuable metals, attributes that arise from their adjustable band gap, exchangeable interlayer anions, substantial specific surface area, and impressive adsorption capacity, making them a promising choice for a wide range of eco-friendly solutions and innovative technologies. 1–6 LDHs are composed of divalent metal ions (M 2+ ) and trivalent metal ions (M 3+ ), as well as anions that aid in charge balancing. These anions, together with water molecules, are accommodated between the layers of the LDH structure.…”

Incorporation of Nanometer-Sized Layered Double Hydroxide with Anions that Improve the Corrosion Resistance of Epoxy Polymer

“…Studies have shown that LDH has great promise for applications in catalysis, − adsorption, − separation, , optics, capacitors, , and biomedicine. , In addition, LDH reduces the concentration of corrosive ions in the environment by trapping corrosive ions such as Cl – between its layers through its intrinsic ion exchange properties, further effectively improving the corrosion resistance of the coating. The two-dimensional layered structure of LDH nanosheets can also fill gaps in the coating, thus reducing the amount of defects and improving the self-healing performance of the coating .…”
