摘要:

采用离子热法合成了一个由八钼酸盐和过渡金属配合物构筑的新颖的三维(3D)自穿插网络的有机-无机杂化材料Cu5BBTZ3H2O[β-MoMo7O26][1,BBTZ=1,4-二(三咪唑-1-乙基)苯]. 化合物1具有由3D聚圆环结构和(4,4)二维层构筑的3D自穿插框架结构. 通过单晶X射线衍射、 元素分析、 红外光谱和热重分析对化合物1的结构进行了表征, 并初步研究了其光催化产氢活性.

Abstract:

A novel hybrid network based on octamolybdate building unit, Cu5BBTZ3H2O[β-MoMo7O26][1, BBTZ=1,4-bis(1,2,4-triazol-1-ylmethyl)benzene], has been synthesized under ionothermal conditions and structurally characterized by single crystal X-ray diffraction. Compound 1 is a rarely self-penetration network constructed by three dimensional(3D) poly-rings networks and (4,4) 2D layers, in which the two interpenetrating parts were united together through Cu2 and Cu1 centers. Further, the infrared(IR) spectrum, thermogravimetric(TG) analysis and photocatalytic studies were also performed to authenticate the identities of the title compound. Photocatalytic study revealed that compound 1 was active for photocatalytic H2 evolution under UV irradiation.

Key words: Octamolybdate, Crystal structure, Photocatalytic, Organic-inorganic hybrid, Ionthermal synthesis
