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

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.
