摘要
The present paper covers seven rare earth-containing tungstosilicate heteropoly complexes LnHSiW_(12)O_(40)·xH_2O with Keggin structure(Ln=La,Ce,Pr,Nd,Sm,Eu and Gd)snythesized by double decomposition reaction.The synthesized heteropoly complexes were characterized by ICP,^(29)Si-NMR,XPS, XRD,IR,UV,polarogram,CV and TG-DTA.The relationship between the structure of the synthesized heteropoly complexes and their properties is discussed.
