| Abstract: | In this paper the synthesis of ten Si-W-V with Keggin structure and seven P-Mo-V with Dawson structure RE heteropoly acid complexes was reported for the first time. The thermal stability of these two series complexes was studied by TG, DTA, IR spectra and X-ray powder diffraction. The regularity of the thermal stability changings of the RE heteropoly acid complexes with the structure of Keggin and Dawson reported in the present literatures was discussed and concluded. |
