摘要
本文首次采用分步酸化，分步加入原料方法制备出新型固体高质子导体钨钒锗酸Ｈ５ＧｅＷ１１ＶＯ４０·２２Ｈ２Ｏ．给出了反应的ｐＨ值和物料的最佳比，用化学分析、电位滴定、ＩＲ、ＵＶ、５１ＶＮＭＲ、Ｘ射线粉末衍射和热分析对合成产物进行了表征．电导率测定结果表明钨钒锗酸是固体高质子导体，室温下其σ值可达１０－３Ｓ·ｃｍ－１．
A new solid high proton conductor tungstovanadogermanic acid H 5GeW 11 VO 40 ·22H 2O has been prepared by stepwise acidification and stepwise addition of materials. The optimal proportion of the materials and the pH of the synthesis reaction are given. The product was characterized by chemical analysis, potential titration, IR, UV, 51 V NMR, X ray powder diffraction and thermal analysis. The determination of conductibility exhibit that tungstovanadogermanic acid is a high proton conductor, its σ value is above 10 -3 S·cm -1 at 18℃.
