Layered double hydroxides (LDHs) have a unique structure and many benefits, which have led to them being widely used in fields such as catalysis, environmental management and medical applications. Typically, soluble metal salts, such as metal nitrates, are used as the starting materials for the synthesis of LDHs, but they are relatively expensive and can be inconvenient to store and transport due to their explosive nature.
