以合成锂皂石(Laponite)为原料,采用微波插层反应制备了铈铝柱撑锂皂石纳米复合材料;通过测定比表面积、FTIR、XRD、TEM、SEM等分析手段,对纳米复合材料的结构进行了表征。结果表明:铈铝能以氧化物的形式柱入锂皂石的结构中,使复合材料形成结晶度更强的层状微晶结构;随着铈铝柱化剂/锂皂石的质量比(Xm)从0.00增加至0.10,锂皂石(Xm=0.00)的比表面积从189.3m2.g-1增大至298.1 m2.g-1,片层结构的层间距d001值由1.3771nm扩大至1.3923nm;随着质量比Xm的增加,片层结构的层面更丰富、片层结晶度也逐渐增强。
Cerium aluminum pillared laponite nanocomposites were prepared by microwave intercalation reaction with Laponite as raw material. The specific surface area, FTIR, XRD, TEM, SEM and other analytical methods were used to fabricate nano-composite The structure was characterized. The results show that cerium aluminum can be precipitated into laponite in the form of oxide to form a layered microcrystalline structure with more crystallinity. With the mass ratio of cerium and aluminum pillared to laponite Xm) increased from 0.00 to 0.10. The specific surface area of hectorite (Xm = 0.00) increased from 189.3m2.g-1 to 298.1m2.g-1, and the d001 value of the interlayer structure increased from 1.3771nm to 1.3923 nm. With the increase of the mass ratio Xm, the lamellar structure is more abundant and the crystallinity of the lamella is also gradually enhanced.
