A new family of polyoxometalates-based inorganic–organic hybrid compounds, namely, [Ag4(H2O)(L)3(SiW12O40)] (1), [Zn(L)(H2O)]2[SiW12O40]·3H2O (2), [Cu(L)(H2O)]2[SiW12O40] (3), and [Cu2(L)2(HPWVI10WV2O40)]·4H2O (4), have been synthesized (L = 1,4–bis(3-(2-pyridyl)pyrazol)butane). This series of inorganic–organic hybrid compounds exhibit variable supramolecular architectures. The photodegradation of
一种基于多金属氧酸盐的无机-有机杂化化合物新家族,即[Ag 4(H 2 O)(L)3(SiW 12 O 40)](1),[Zn(L)(H 2 O)] 2 [SiW 12 O 40 ]·3H 2 O(2),[Cu(L)(H 2 O)] 2 [SiW 12 O 40 ](3)和[Cu 2(L)2(HPW VI 10 W V 2 O 40)]·4H 2 O(4),已经合成(L = 1,4-双(3-(2-吡啶基)吡唑)丁烷)。这一系列的无机-有机杂化化合物表现出可变的超分子结构。有机染料的光降解孔雀绿和亚甲蓝与使用的化合物的1 - 4作为光催化剂被可见光照射下的研究。令人惊讶的是,光催化结果表明化合物1是用于去除孔雀石绿和亚甲基蓝的有效光催化剂。值得注意的是,化合物1可用作活性和可回收的光催化剂,用于还原Cr VI在室温下用异丙醇作为清除剂。苯硫基甲烷的催化氧化脱硫还研究了与使用的化合物1 - 4
