摘要：

A new Cu metal-organic framework (Cu-MOF), [Cu(adp)(BIB)(H2O)](n) (BIB = 1,4-bisimidazolebenzene; H(2)adp = adipic acid), is synthesised under hydrothermal conditions. Single-crystal X-ray analysis reveals a three-dimensional supramolecular architecture with channels originating from two-dimensional layers extended by hydrogen bonds. The cyclic voltammogram of a [Cu(adp)(BIB)(H2O)](n)-modified electrode shows a pair of redox peaks at ca. 0.43 V in 0.1 M NaOH solution corresponding to Cu-III(OH)-MOF/Cu-II(H2O)-MOF couple. The Cu-MOF-modified electrode shows high electrocatalytic activity towards H2O2 oxidation with a linear range from 0.1 mu M to 2.75 mu M and a detection limit of 0.068 mu M. Thus, Cu-MOF is a promising material for H2O2 detection. (C) 2013 Elsevier B.V. All rights reserved.
