Hydrotalcite, also known as Layered Double Hydroxides (LDHs), is an important catalyst carrier material. It is composed of layered stacking of metal ions and hydroxide ions, with a typical brucite structure, where metal ions are usually a mixture of divalent and trivalent ions, such as magnesium, aluminum, nickel, cobalt, etc.

Hydrotalcite exhibits excellent performance in the field of catalysis due to its unique layered structure and controllable composition. Its large specific surface area is conducive to adsorbing reactants, and the interlayer anions can be adjusted through ion exchange to meet the needs of different catalytic reactions. In addition, hydrotalcite also has good thermal stability and acid-base stability. When used as a catalyst carrier, it can effectively protect the active components, improve the stability and service life of the catalyst.
