FTIR and XRD show that PW12O403- has been incorporated into the interstitial space with the dimension of 0.917 nm. The state of PW12O403- anion between the hydrotalcite sheets was also discussed. The title product can be expressed by formula [Zn0.68Al0.32(OH)2]×[PW12O40] 0.11×3H2O after a serious study of TGA and chemical analysis. %U https://www.jproeng.com/CN/abstract/article_1115.shtml
