Transition metal-based layered double hydroxides (LDHs) represent a versatile and highly tunable class of materials with significant potential across various scientific and industrial fields. These materials, characterized by their unique layered structures, consist of positively charged layers of mixed metal hydroxides, typically featuring divalent and trivalent metal cations, separated by interlayer anions and water molecules. The incorporation of transition metals such as Ni, Co, Fe, and Mn into LDH frameworks has led to a wide range of functionalities, making them valuable in applications including catalysis, energy storage, environmental remediation, and biomedical devices.
