XRD indicated that the replacement of the terephthalate anion by the polytungstate anion had little effect on the structure.

结果表明，经过同多钨酸根阴离子的交换以后，垂直于水滑石层板方向的平行层板方向的晶格参数值变小，平行层板方向的晶格参数值不变，(003)、(006)、(009)衍射峰处的层间距值比为3：2：1；交换过程没有改变水滑石的结构，水滑石原位生长在γ-Al2O3表面及内孔，比表面积由γ-Al2O3载体的219m2/g增加到247m2/g，孔径分布则由原来的2～11nm变化为3～4nm。
