Abstract
<jats:p>Layered double hydroxides (LDHs) belong to a class of anionic clays having lamellar structure and tunable properties. This book chapter focuses on different properties of LDHs, such as their thermal stability, acidity, alkalinity, anion exchange capacity, exfoliation and assembly, and other morphological properties. The properties of LDHs vary greatly depending upon the chemical composition and synthetic route. Various synthesis methods and their advantages and disadvantages are discussed, including sol–gel, hydrothermal, co-precipitation, and other processes. This work also presents numerous modification strategies, such as anion exchange, doping, and composite construction, that enhance the functionalization of LDH materials and make them promising candidates for diverse real-life applications. Additionally, recent work by researchers in exploring applications of LDHs in agriculture, drug delivery, tissue engineering, biomedical implants, environmental remediation, catalysis, sensors, and the energy sector are summarized in this chapter. In short, this book chapter critically analyzes the properties, modifications, and synthesis methods of LDHs and their significant applicability in many fields.</jats:p>
