CoFe-MOF nanoarray as flexible microelectrode for electrochemical detection of catechol in water samples.

ABSTRACT: A simple, selective, and straightforward enzyme-free electrochemical sensor has been designed and developed using cobalt hexacyanoferrate metal-organic framework (CoFe-MOF) nanoarray. The prepared CoFe-MOF nanoarray has been successfully grown over a carbon cloth (CC) to form CoFe-MOF/CC as a flexible microelectrode for the detection of catechol. The surface of the activated CC was covered uniformly with CoFe-MOF in the form of nanoarray and exhibited double-shelled cubic morphology. The CoFe-MOF/CC nanoarray microelectrode showed a pair of well-defined redox peaks corresponding to the [Fe(CN)₆]^4-/3- redox signal. Interestingly, the fabricated nanoarray microelectrode has displayed superior peak current at lower onset potential with high electrochemical response compa
