摘要
利用无机溶胶 -凝胶法制备复合钒钼酸 H2 V12 - x Mox O31± y· n H2 O(0≤ x≤ 3 )干凝胶薄膜 ,并对其进行 TGA,XRD,XPS,X射线能谱及线扫描组分分析 . x=0和 x =2 .5的H2 V12 O30 .7· 8.4H2 O和 H2 V9.5Mo2 .5O32 .0 · 9.2 H2 O干凝胶薄膜均具有层状结构 ,复合钒钼酸凝胶中的 V和 Mo分别以 V5+和 Mo6 +形式存在 ,且均匀地分布 .
The xerogel thin film from hydrated compounds H 2V 12- x Mo x O 31± y · n H 2O( x=0, x =2 5) formed by sol gel technology were investigated by TGA, XRD, XPS and X ray spectrum. The TGA and XRD results show that the compounds have a layered structure and the formulas are H 2V 12 O 30.7 ·8 4H 2O and H 2V 9.5 Mo 2.5 O 32.0 ·9 2H 2O, respectively. The shape and location of the photoelectric lines of V 2 p , Mo 3 d and O 1 s were analyzed for H 2V 9.5 Mo 2.5 O 32.0 ·9 2H 2O samples, and the results show that V and Mo in the samples should exist in the form of V 5+ and Mo 6+ ions .They were well distributed in the films.
