ABSTRACT MgAl LDHs intercalated with CO(NH 2 ) 2 , NH 4 Cl and NH 3 ·H 2 O were prepared by co-precipitation and XRD, FT-IR, TGA-DTA and SEM techniques were employed for characterization. The results indicated that the layer-layer spacing of LDHs was enlarged by 0.169, 0.285 and 0.227 Å with the intercalation of CO(NH 2 ) 2 , NH + 4 and NH 3 , separately. The effects on thermal stability and degradation behavior of synthesized LDHs where mole ratios...
