摘要：

A well-crystallised [Zn-Al-Cl] layered double hydroxide was prepared by coprecipitation at constant pH. The chloride ion of this solid was then exchanged in solution with a series of phosphate ions having different sizes and charges; namely, PO3-, H2PO4-, HPO42-, PO43-, P2O74- and P3O105-. Powder X-ray diffraction and Fourier transform infrared spectroscopy have allowed a correlation to be made of the structural features of the precursor and the exchanged materials.
