Abstract

A new Zn(II)-based metal-organic framework (MOF) with formula [Zn2(NH2-BDC)2(H2O)] (1) (NH2-H2BDC = 2-aminoterephthalic acid), has been synthesized solvothermally and characterized. The single crystal X-ray diffraction indicated that 1 possess a 3D framework with a (44·62)2(43) topology. Also, the MOF exhibit efficient photocatalytic performance to photodegrade methyl violet (MV) under UV light. In presence of 1, 67.31% degradation of MV after 40 min has been observed. The intermediate as well as final degradation products of MV have been identified using LC–MS and the plausible photodegradation pathways of dye are discussed. In addition, the plausible photocatalytic mechanism been explained with the help of theoretical calculations using density of states.
