摘要: 通过磷酸氢二钠、 偏钒酸钠、 钼酸钠溶液混合制备具有 K e g g i n结构的磷钼钒杂多酸 H5PMo 1 0V2O4 0,并将其与1 - 丁基 - 3 - 甲基咪唑溴离子液体反应, 合成[ Bm i m] 5PMo 1 0V2O4 0杂多酸催化剂, 并利用傅里叶红外光谱、 X射线衍射对合成产物的结构进行表征。结果表明, 合成的[ Bm i m] 5PMo 1 0V2O4 0杂多酸杂化材料具有 K e g g i n结构。考察了负载量、 反应温度、 H2O2体积、 催化剂质量对降解率的影响。实验结果表明, 最佳反应条件为: 负载量为3 0%、 反应温度为4 0℃、 H2O2体积为1. 5mL、 催化剂质量为0. 2g。按照最佳反应条件进行反应, 罗丹明B降解率最高可达9 7. 5 8%。合成的催化剂具有很好的重复使用性, 重复使用4次, 罗丹明B的降解率没有明显下降。

Abstract: The  H5PMo 1 0V2O4 0 with Keggin structure was prepared by mixing Na2HPO4, NaVO3, and Na2MoO4•2H2O in stoichiometric amount. Then the \[ Bm i m] 5PMo 1 0V2O4 0 hybrid materials was prepared by reacting H5PMo 1 0V2O4 0 with the 1butyl3methyl imidazolium bromide ionic liquid. The IR spectra and XRD data showed that the synthetic \[Bmim\]H5PMo 1 0V2O4 0 hybrid materials display Keggin structure. The SiO2supported \[Bmim\] 5PMo 1 0V2O4 0 hybrid materials were obtained, and the prepared samples were applied to the catalytic degradation of organic dyeRhodamine B. The optimal reaction condition was 30% of \[Bmim\] 5PMo 1 0V2O4 0/SiO2 loading, 1.5 mL of hydrogen peroxide, 0.2 g of the catalyst at 40 ℃. Under the optimal conditions, the highest degradation rate of organic dye Rhodamine B reached up to 97.58%. The catalyst show good regeneration performance, which can be reused at least four times and the degradation rate of Rhodamine B was no significant declined. 
