Synthesis of Hydrotalcite-like Compound Pillared by Hetero-polyacid Anions in a Hydrothermal System

Hetero-polyacid anions (PW12O403()-pillared hydrotalcite-like compound is directly and hydrothermally synthesized by the hot solution method. 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.
