| Summary: | Synthesis of new hybrid nanocomposite material zinc-aluminium-9-hydroxy-9-
fluorenecarboxylate was successfully accomplished by self assembly method with molar
ratio of Zn to Al ; R= 2 at various concentration of 9-hydroxy-9-fluorenecarboxylate
ranging from 0.2 M to 0.8 M . The pH of the synthesis was kept constant at 7.5. As a
result of the successful intercalation of 9-hydroxy-9-fluorenecarboxylate anion into zincaluminium-
layered double hydroxide, an expansion of the interlayer spacing from 8.9 Å
in the layered double hydroxide to 14.3 Å in the zinc-aluminium9-hydroxy-9-
fluorenecarboxylate nanocomposite could be observed in the PXRD diffractogram. The
percentage loading of the guest anion, 9-hydroxy-9-fluorenecarboxylate in the layered
double hydroxide was estimated to be about 76-78% (w/w) at the optimum condition |
