Synthesis and photo-/electro-catalytic properties of 3D POMOF material based on interpenetrated copper coordination polymer linked by in-situ dual-ligands and Dawson-type phosphotungstate

Abstract

A novel 3D polyoxometalate metal organic framework (POMOF), [{Cu6IICu10I (H2O)5(pzc)10(pz)6}{P2 W18O62}2]•4H2O (1) (Hpzc = pyrazine-2-carboxylic acid, pz = pyrazine) has been hydrothermally synthesized and characterized by IR, TG, XRD, UV-Vis and elemental analysis. In compound 1, the pzc and pz ligands are generated through in-situ transformed from pyrazine-2, 3-dicarboxylic acid (pzdc) to remove one or two CO2 molecule. The ligands with four coordination modes connect nine crystallographically independent Cu atoms to form a super-big circle unit. Each ring unit is connected to the adjacent six rings via edge-sharing way to form 2-D Cu/pz/pzc MOF layer, which is further extended along two spatial directions by two kinds of insert mode to generate a interpenetrating and staggered 3-D metal organic network. The {P2W18} clusters as nine-node inorganic guest molecule are grafted on the Cu/pz/pzc framework forming a complex 3D POMOF with new topology {4•6•83•10}2 {4•6•8}2 {4•62•82•10}2{4•63•82}2{4•85}2{42•62•82}2{42•63•8}{43•67•813•1010•123}2 {4}6{6•82}2{62•8}2 {64•8•10}{6}2{8}4. Additionally, compound 1 exhibits merit electrocatalytic activity for reduction of H2O2 and effective photocatalytic degradation abilities for three azo dyes under UV irradiation.
