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。

It is concluded that ions are condensed gradually in the process of heat treatment polytungstate acid,the symmetry of the WO6 octahedral is improved and the strength of the WOWbond is increased.

TG-DTA和IR分析结果表明,随着热处理温度的提高,薄膜中多聚钨酸离子进一步缩合,WO6八面体对称性逐渐增强。

A terephthalate anion-pillared Ni-Al hydrotalcite-like layered double hydroxide was synthesized on the surface and within the pores of γ-Al 2O 3 by in situ crystallization and a polytungstate anion-pillared hydrotalcite was subsequently obtained by ion-exchange.

采用原位沉积法在γ-Al2O3表面原位合成了对苯二甲酸阴离子柱撑的镍铝水滑石,并用同多钨酸根阴离子部分交换了镍铝水滑石中的对苯二甲酸阴离子。

WO3, an interlayer compound prepared by J. W. Johnson (1981) using yellow tungstic oxide hydrate. Suspension of white powdery tungstic acid in anhydrous pyridine yields on standing for 2 wk whiteHW4O13.3H2O. IR and DTA studies revealed the connection between that pyridine polytungstate and white powdery tungstic acid (microcryst.), whose composition may thereby be assigned as H2W4O13.nH2O.

WO3。粉状白钨酸在无水吡啶中放置两周后可得到另一种化学式为(C5H5NH)HW4O13.3H2O的吡啶化合物,经IR和DTA研究可初步说明该化合物与粉状白钨酸之间的联系,并因此推测白钨酸的组成可能为H2W4O13.nH2O。
