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.
