含铝多孔粘土材料的合成与研究
STUDY ON THE SYNTHESIS OF ALUMINUM POROUS CLAYS
【摘要】 本文利用XRD、TEM等方法初步研究 2∶1型蒙脱石矿物及 1∶1规则间层的累脱石矿物与聚合羟基铝交联剂的层间交联作用 ,比较了不同制备条件下对形成含铝多孔粘土材料孔结构性质的影响。结果表明 ,适当增加Al/土值、采用PVA表面活性剂对粘土进行修饰改性有利于形成具有大孔结构的材料。
【Abstract】 The interlayered crosslinking of a 2∶1 layer montmorillonite and a 1∶1 layer of rectorite with a polyoxocation of Al was investigated by means of XRD and TEM. The impact of preparation conditions on the pore structure of porous clays was also discussed. The results showed that a high ratio of Al/clay or the use of a PVA(polyvinyl alcohol) precursor is beneficial to the formation of porous clays with a large-pore structure.
