1:12系列钼钨磷混配型杂多酸(盐)的合成及性质研究
摘要:
用分步法制备出高纯度、高产率的混配型钼钨磷杂多酸H3PMo6W6O40·xH2O晶体,并合成出4种通式为Ln[PMo6W6O40]·xH2O(Ln=La,Ce,Pr,Nd)钼钨混配型稀土杂多酸盐及ZnHPMo6W6O40·xH2O杂多酸盐。

PREPARATION AND CHARACTERIZATION OF 1:12 SERIES OF HETEROPOLY MOLYBDOTUNGSTOPHOSPHORIC ACIDS(SALTS)
Abstract:
Heteropoly molybdotungstophosphoric acids (salts) with formula Ln-PMo6W6O40·xH2O (Ln=La, Ce, Pr, Nd) and ZnHP Mo6 W6O40·xH2O were prepared and characterized by elemental analysis, IR, UV spectrometry, and x-ray diffraction.The thermal stabilities of the compounds were as follows:solid acids > rareearth salts > Zn salt.The mechanism of reduction of the heteropolyanion in aqueous solution was proposed.
