Layered Double Hydroxides (LDHs), also known as anionic clays or hydrotalcite-like compounds, are a class of materials characterized by their unique layered structure. They consist of positively charged metal hydroxide layers and charge-balancing anions in the interlayer spaces. LDHs can be represented by the general formula [M1-x2+Mx3+(OH)2]x+[An-]x/n·mH2O, where M2+ and M3+ are divalent and trivalent metal cations, and An- is an anion.
