Layered Double Hydroxide Materials: A Review on Their Preparation, Characterization, and Applications

Layered double hydroxides (LDHs), a type of synthetic clay with assorted potential applications, are deliberated upon in view their specific properties, such as adsorbent-specific behavior, biocompatibility, fire-retardant capacity, and catalytic anion exchange among others. LDHs materials two-dimensional morphology, high porosity, exceptionally tunable exchangeable anionic particles sensible interlayer spaces. The remarkable feature is flexibility maintaining the spaces endowing them capacity to accommodate variety ionic species, suitable for many applications. Herein, some methodologies, general characterizations, applications summarized, encompassing broader appliances material serve society address several problems viz. removal pollutants fabrication sensors multifaceted useful medical, electrochemical, catalytic, agricultural fields,
