Layered inorganic structure such as Layered Double Hydroxide (LDH), zinc layered hydroxide (ZLH) and graphene, in nano-size, have been used widely in the nanotechnology areas as a new and promising problem solving materials. The ability of these inorganic layered compounds that able to encapsulate the organic anions were known to provide greatest benefits; were explained more details in this paper. Intercalations of anion into the interlayer spaces of layered inorganic structure such as anion-exchange, co-precipitation, hydrothermal method and reconstruction with ‘memory effect’ were also explained. The characterization of intercalated layered nanocomposites such as Fourier Transforms Infrared (FTIR) spectroscopy, PowderX-ray Diffraction (PXRD) analysis, Thermogravimetric analysis, surface analysis was used to explain the successful of anion intercalated in between the interlayer spaces of layered inorganic structures. The application of these hybrids that have been widely used such as controlled release properties in pharmaceutical area, antimicrobial studies, dyeing agent, enhancing UV Sunscreen protection, herbicides and water treatment process were also described in details. © 2021, ASM Science Journal.
