摘要
LDHs(Layereddoublehydroxides)是一类阴离子层状化合物,具有碱性和酸性的特征、层间阴离子的可交换性、微孔结构和记忆效应。本文简单介绍了LDHs材料的结构、性能及生成机理,主要概括、分析了LDHs的制备方法,探讨了LDHs合成反应的主要工艺参数对产品纯度、结构的影响。LDHs材料主要通过盐和碱反应、盐和氧化物反应和离子交换反应制得。文章指出了当今LDHs的研究动态和发展前景,为LDHs材料的研究提供参考。
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.
