Azoic Dye Hosted in Layered Double Hydroxide: Physicochemical Characterization of the Intercalated Materials

We fabricated new magnetic material CuFe2O4/Zn2Cr-LDH by the combination of CuFe2O4 and layered double hydroxide (LDH) through two steps. CuFe2O4 was prepared by sol-gel method with the assistant of citric acid, which was used in synthesis of the composite via microwave hydrothermal method subsequently. The physicochemical properties of the composite was characterized by several techniques, such as X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, Vibrating sample magnetometer (VSM) and Thermogravimetry-differential thermal analysis (TG-DTA). The magnetic composite reveals several advantage of LDH structure and spinel ferrite oxide and is potential for the application of heterogeneous catalysis.

A new magnetic Fe3O4/MO-intercalated-LDH composite has been synthesized by combination of Fe3O4, layered double hydroxide (LDH) and methyl orange (MO). Fe3O4/Zn2CrLDH and Fe3O4/MO-intercalated-LDH were obtained via two-step microwave hydrothermal and anion exchange method. X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and vibrating sample magnetometer (VSM) were conducted to characterize the as-prepared samples. The latter exhibited that basal spacing of Zn2Cr-LDH is 1.18 nm. The value of saturation magnetization (Ms) is 20.5 emu/g. In addition, the amounts of adsorbed MO reached 1.54 mmol/g. Therefore, the material shows several advantages for the removal of pollutants.

Double Hydroxide

A nonsteroidal drug, flufenamic acid (FA) was successfully intercalated into magnesium-aluminium-layered double hydroxide, MAL for the formation of magnesium-aluminium-flufenamate-layered double hydroxide, MAF by self-assembly technique. As a result of the successful intercalation, basal spacing increased from 9.8 Å in the MAL to 23.5 Å in the MAF hybrid nanocomposite. The FTIR spectra of the MAF hybrid nanocomposite show resemblance peaks of the MAL and FA suggesting the inclusion of the organic compound into the MAL interlamellae. The percentage loading of FA was found to be 74.4 % (w/w) calculated from the percentage of carbon in the resulting material, MAF.
