| Abstract: | LDHs(Layered double hydroxides)were layered anionic clays with acid properties, basic properties, interlayer anionic exchangeability and adjustability, micropore structure and memory effect. The structure, capability, synthetic mechanism of hydrotalcites were simply presented. The preparation methods of hydrotalcites were summarized and analysed, and the effects of main technological parameters in the synthesis on the purity and the structure of the products were remarked. LDHs were prepared by reactions between salts and alkalis, salts and oxides and ion-exchange reactions. The present situation and prospect in the research field are outlined. |
