| Abstract [eng] |
The Mg3/Al1 and Mg3-xMx/Al1 (M = Mn, Co, Ni, Cu, Zn) layered double hydroxides (LDHs) were synthesized using sol-gel synthesis technique. The intercalation with different organic anions (formate (HCOO−), acetate (CH3COO−), oxalate (C2O4 2−), tartrate (C4H6O4 2−) and citrate (C6H5O7 3−)) using ion exchange approach was investigated. The influence of ultrasound and cation substitution on the intercalation of organic anions to the Mg3/Al1 LDH has been investigated. The obtained results indicated that ultrasound has a positive effect in some cases for the intercalation of organic anions into the Mg3/Al1 LDH system. On the other hand, the substitution of magnesium by transition metals has negligible effect on the intercalation process. The synthesized and intercalated LDHs were characterized by X-ray diffraction (XRD) analysis, infrared (FTIR) spectroscopy, Raman spectroscopy, thermal (TG-DTG-DCS) analysis and scanning electron microscopy (SEM). |
