摘要
采用改进分步合成的方法,首次制备了2:18系列的钨钛磷三元混配杂多酸盐。用元素分析、^(31)P核磁共振谱、极谱、循环伏安、红外光谱、紫外光谱、x射线衍射、x光电子能谱、热重—差热分析对它进行了表征,确定杂多酸盐的组成为K_8[P_2W_(17)TiO_(62)]·12H_2O。杂多阴离子具有Dawson结构。对产物的光谱性质、氧化还原性质和热稳定性进行了探讨。
The work reported here was concerned the prepartion of salt of (2 : 18) heteropoly complex of tungstotitanophosphate with the method of improved sequence preparation . The structure of the complex was investigated by elemental analysis,31PNMR Spectra,polarography, Cyclic - voltam-metry, IR,UV,X-ray powder diffraction,X -photoelectron spectra and TG -DTA analysis. The results showed that this complex was K8(P2W17TiO62) 12H2O and the structure was consistent with the Dawson structure. The Properties such as spectra,redox and thermal stability were discussed.
