Assembly and Structural Characterization of Terephthalate-pillared Hydrotalcites
Abstract:
Terephthalate-pillared hydrotalcites, Mg4Al2(OH)12[C6H4(COO)2], were successfully synthesized through Mg4Al2(OH)12CO3·4H2O precursor in an organic solvent by ion exchange. The samples thereby obtained were characterized by XRD, FT-IR and DTA. The results show that the initial interlayer carbonates of the hydrotalcite can be completely replaced by terephthalic anions under special controlled conditions. The pillared hydrotalcites have good layered structure and the interlayer distance varies slightly (1.38~1.45 nm) with the exchange temperature (70~150℃). The interlayer terephthalic anions decompose at about 553℃.
