Synthesis and Photocatalytic Performance of A Novel Keggin Compound { [Et3N]5[H3BW12O40]2·2H2O}
【摘要】 以三乙胺,钨酸钠,硼酸和硝酸铜为原料,采用水热法合成了一个新型的簇合物[Et3N]5[H3BW12O40]2·2H2O（1,CCDC:932 982）,其结构和性能经UV-Vis,X-单晶衍射,FT-IR,元素分析,XRD,XPS,TGA和CV表征。结果表明:1具有新颖的三维超分子网络结构;在602℃时,1的失重率约15.53%;1催化降解甲基橙结果表明:1的光催化活性较好,甲基橙降解率由100%降至41.6%,降解速率为11.68%·h-1。
【Abstract】 A novel polyoxometalate,[Et3N]5[BW12O4]2·2H2O（ 1,CCDC: 932 982）,was prepared by hydrothermal method,using Et3 N,Na2WO4·2H2O,H3BO4 and Cu（ NO3）2as materials.The structure and properties were characterized by UV-Vis,FT-IR,elemental analysis,XRD,XPS,TGA and CV. The results showed that 1 was in 3D supramolecular structure. The weight loss ratio of 1was 15. 53% at 602 ℃. The results of 1 catalytic degradation methyl orange indicated that 1 exhibited good photocatalytic property. The degradation ratio decreased to 41. 6% from 100% with degradation rate of 11. 68% ·h-1.
