摘要：

The Art particles have been intercalated within the gallery spaces of Zn-Al layered double hydroxides (LDHs). Synthesis of this material was obtained by ion-exchange of the LDH-nitrate precursor with AuCl4- anion followed by reduction with the sodium citrate. Elemental analysis, X-ray diffraction, X-ray photoelectron spectroscopy (XPS), TEM and N-2 sorption analyses have been used to characterize the material. TEM micrographs of LDH-Au revealed a typical porous material. Chemical analysis results showed that AuCl4- anions exchanged with nitrate anions. XPS analysis confirmed the deoxidization of the AuCl4- anions in the gallery after treatment with the sodium citrate. The XRD diffraction patterns of LDH-Au revealed that the layer structure is maintained after all synthetic steps. The XPS spectra, the elemental results and the TEM patterns proved the intercalation of Au particles into the gallery. (c) 2005 Published by Elsevier B.V.
