| 摘 要： | 通过水热反应,成功合成了一个草酸配体修饰的四核锆取代的夹心型硅钨-氧簇合物H12Na2Zr4(μ3-O)2(μ2-OH)2(Ox)2(α-SiW10O37)2]·22H2O (Ox=oxalic acid)。该夹心型硅钨-氧簇是由两个{α-SiW10O37}簇块通过一个{Zr4(μ3-O)2(μ2-OH)2(Ox)2}簇连接构成的。通过X-射线单晶衍射、IR、TG以及元素分析对该簇合物进行表征。晶体结构分析表明: 该簇合物结晶于单斜晶系,P21/c空间群,a=2.132 2 (6) nm, b=1.271 6 (4) nm, c=2.223 1 (7) nm, β=110.933(4)°,V=5.629 9(3) nm3,Z=2,R1=0.061 5,wR2=0.164 4。电化学和电催化性质研究表明标题簇合物对NO-2的还原有很好的电催化效果。

| Abstract: | Under hydrothermal conditions,a new Ox-functionalized zirconium(Ⅳ) substituted tungsten-oxo cluster, H12Na2Zr4(μ3-O)2(μ2-OH)2(Ox)2(α-SiW10O37)2]·22H2O (Ox=oxalic acid) was successfully obtained and characterized by single crystal X-ray diffraction analysis, IR, TG and elemental analysis. The title compound consists of a sandwich-type tungsten-oxo cluster unit built by two divacant {α-SiW10O37} fragments linked through a {Zr4(μ3-O)2(μ2-OH)2(Ox)2} cluster and crystallizes in the monoclinic system, space group P21/c with a=2.132 2 (6) nm, b=1.271 6 (4) nm, c=2.223 1(7) nm, β=110.933(4)°, V=5.629 9(3) nm3, Z=2, R1=0.061 5, wR2=0.164 4. The electrochemistry and electrocatalytic properties of the title compound were studied, and it exhibits excellent catalytic activities for NO-2 reduction. |
