In this paper, the intercalation of methyl-orange (MO) into Mg/Al (ratio=2:1) layered double hydroxide (LDH) was carried out using reconstruction method to obtain MOLDH nanocomposite material. Its chemical composition, crystal structure, appearance and thermal stability were characterized by XRD, FT-IR, TEM, TG-DTA and element analysis. It has been found that the MOLDH still keeps the typical lamellar structure, and the guest MO has been intercalated into the layers of the host LDH. The MOLDH's disassembly temperature is higher more than 30 C than that of guest molecule MO, so it can be used as a new dye with high thermal stability.

Keywords:methyl-orange (MO); layered double hydroxide (LDH); nanocomposite; intercalation; dye
