A new Zn( ii )-based 3D metal–organic framework with uncommon sev topology and its photocatalytic properties for the degradation of organic dyes

A new d 10 -configuration based Zn( ii ) 3D metal–organic framework (MOF) with the formula {[Zn 4 (NDC) 3.5 (μ 4 -OH)(DMF)]·1.7DMF} n ( 1 ) has been synthesized using a 1,4-naphthalenedicarboxylic acid (H 2 NDC) ligand and characterized. The single crystal X-ray diffraction results indicate that in...

Description
Summary:A new d 10 -configuration based Zn( ii ) 3D metal–organic framework (MOF) with the formula {[Zn 4 (NDC) 3.5 (μ 4 -OH)(DMF)]·1.7DMF} n ( 1 ) has been synthesized using a 1,4-naphthalenedicarboxylic acid (H 2 NDC) ligand and characterized. The single crystal X-ray diffraction results indicate that in the newly synthesized MOF, 7-connected [Zn 4 (μ 4 -OH)(COO) 7 ] clusters are formed which are extended by NDC 2− ligands to generate an uncommon sev topology. The photocatalytic properties of 1 in the photodegradation of model organic dyes viz. methyl violet (MV) and rhodamine B (Rh B) have been systematically investigated. The photocatalysis results demonstrated that 1 shows promising photocatalytic degradation activity against these organic dyes. The possible photocatalytic mechanism through which 1 displayed photocatalytic properties to photodegrade organic dyes has also been proposed with the aid of density of states (DOS) calculations.
