Multifunctional Gas Adsorption and Photocatalytic Degradation Based on a Porous Metal-Organic Framework Material

Abstract

The reaction of Cu(NO3)2 · 3H2O with rigid ligand 4'-(1H-tetrazol-5-yl)-[1,1'-biphenyl]-3,5-dicarboxylic acid (H3L) gave a new metal-organic framework of [Cu2(μ3-OH)(L)(H2O)2] n (I) (CIF file CCDC no. 1533273). Complex I has a truncated cuboctahedra that was connected by trigonal Cu3O(N4CR)3 trimers using each tetrazolate (N4CR) moiety and shows a overall 3D nnt net with (6.82)6(83)2(62.84)3 topology. The properties of gas adsorption and the degradation of the methyl violet have been examined.
