羟基铝镍多孔粘土材料的表面酸性及其孔容

The Surface Acidity and Porosity Volume of Hydroxy Al Ni Porous Clay Materials

把羟基铝镍聚合物引入蒙脱石层间，制备多孔粘土材料，利用ＸＲＤ、ＩＲ及非水溶液滴定法研究了制备方法及条件变化对材料表面酸性及孔容的影响。结果表明，制备方法及ＡｌＮｉ、（Ａｌ＋ Ｎｉ）土、老化温度等条件对表面酸性及孔容均有影响，材料在４００

Hydroxy Al Ni oligocations were brought into interlamellar space of montmorillonites to prepare porous clay materials. The effects of preparation methods and conditions on the surface acidity and porosity volume were studied by XRD,IR and nonaqueous solution titration etc. The results have shown that preparation methods, Al/Ni, (Al+Ni)/clay and ageing temperature have greater effect on the surface acidity and porosity volume. This materials showed a higher thermal stability at temperatures up to 400℃.
