摘 要
本文介紹了多金屬氧酸鹽，簡單闡述了多金屬氧酸鹽在催化、藥物、材料等方面的應(yīng)用。用常規(guī)法合成了12-鉬磷酸（H3PMo12O40•nH2O）、18-鎢-2-磷酸鉀（K6[P2W18O62] •14H2O）、Dawson型單缺位17-鎢-2-磷酸鉀（K10[α-P2W17O61] •20H2O）、Keggin型單缺位11-鎢磷酸鉀（K7PW11O39），并對其進(jìn)行IR表征。因其陰離子是很好的配體，使其與過渡金屬Co2+聚合得到紅色塊狀晶體，并對其進(jìn)行了IR表征。

ABSTRACT
This paper introduces the polyoxometalates, and briefly expounds the polyoxometalates more in catalytic, oxygen acid drug, materials, and other aspects of the application. With conventional synthesis method of the 12-molybdenum phosphoric acid(H3PMo12O40),18-tungsten-2-potassium phosphate (K6 [P2W18O62] • H2O), Dawson model sheet vacancy 17-tungsten-2-potassium phosphate (K10 [α-P2W17O61] • 20 H2O), Keggin model sheet vacancy 11-tungsten potassium phosphate (K7PW11O39), and the IR characterization. Because of the anion is very good ligands, make its and transition metal Co2 + polymerization get red massive crystals, and analyses the IR characterization.
Keywords: polyoxometalates; synthesis; structure characterization; application
