Since 2013, MOFs-based electrochemical sensors have been developed at an exponential rate. Electrochemical methods integrated with MOF-modified electrodes can be applied to detect a large number of molecules, including heavy metal ions, biomolecules, and even volatile compounds with sufficient sensitivity and selectivity. The fabrication of a good MOF-based electrochemical sensor depends on many factors since every step from the point of synthesis of the MOF to fabricating an electrode for electrochemical detection is critical. The selection of correct electroactive MOF and these electrode fabrication steps also contribute to the performance of the sensor. However, poor electrical conductivity and poor chemical stability of MOFs in solutions are the main challenges to be overcome in the MOF-based electrochemical sensor field. This chapter discusses the fabrication of MOF-based electrodes, various types of MOF composites synthesized to overcome drawbacks associated with MOFs, detection of various types of molecules including heavy metal ions and biomolecules, and finally, challenges associated with MOF-based electrochemical sensors.
