Synthesis and Characterization of Methyl-Red/Layered Double Hydroxide (LDH) Nanocomposite
In this paper, the intercalation of methyl-red (MR) into Mg/Al (ratio=2:1) layered double hydroxide (LDH) was carried out using reconstruction method to obtain MRLDH nanocomposite material. Its chemical composition, crystal structure and appearance were characterized by XRD, FT-IR, TEM, TG-DTA and element analysis. It has been found that the MRLDH still keeps the typical lamellar structure, and the guest MR has inserted into the layers of the host LDH. The MRLDH’s disassembly temperature is higher more than 70°C than that of guest molecule MR, so it can be used as a new dye with high thermal stability.
