Abstract

Neutral ethylene glycol (EG) molecules have been intercalated into zinc hydroxide layers to produce a new hybrid material in which only one kind of metal ion is included. Initially, layered basic zinc acetate (LBZA, Zn ₅(OH)₈(CH₃-COO)₂·2H ₂O) was prepared from a methanolic zinc acetate dihydrate solution. The immersion of LBZA in EG resulted in its intercalation, which was accompanied by an interlayer expansion of 7.12 Å, as revealed by X-ray diffractometry. A Fourier transform infrared spectroscopic study indicated that the new compound contained both the acetate groups and the EG molecules. Together with thermogravimetry-differential thermal analysis, a composition of the new compound was estimated to be Zn₅(OH)₈(CH ₃COO)₂(HOC₂H₄OH)₂· 2H₂O. The EG intercalation was found to increase the dehydration temperature of the zinc hydroxide layers from 130 to 180°C. So the thermally stable material is then promising as a new class of precursors in creating organic-inorganic nanocomposites.
