摘要

A redox-active Cu-based metal-organic framework (Cu-MOF) was prepared via a facile solvothermalsynthesis. The electrochemical and electro-catalytic properties of the as-prepared Cu-MOF wereinvestigated in pH 7.2 phosphate buffer solution (PBS) by casting the material on a carbon pasteelectrode (CPE) (Cu-MOF/CPE). The Cu-MOF exhibited high stability and well-behaved redoxevents. It also showed strong absorption ability towards electro-active probe ferricyanide ion3- 3- 3- (Fe(CN)6 ), allowing the efficient immobilization of Fe(CN)6 on the electrode (Fe(CN)6 /Cu- 3- MOF/CPE). The Fe(CN)6 /Cu-MOF/CPE presented significantly enhanced electro-catalytic activitytowards the oxidation of nitrite. The Cu-MOF was first demonstrated for the electrochemical sensingapplication in the determination of nitrite, which showed excellent sensing performances. The resultsindicated that the Cu-MOF offer a promising candidate applied in electro-catalysis and electro- analysis.
