Metal–organic framework-based sensors for the detection of heavy metal ions in water

Abstract

Metal–organic frameworks (MOFs) have shown significant potential for the detection of heavy metal ions due to their high designability, large specific surface area, and tunable porous structures. This review focuses on the recent advances in the detection of heavy metal ions, highlighting the various detection mechanisms (such as fluorescence quenching/enhancement, electrochemical and colorimetric) based on MOFs. Furthermore, the limitations and prospects of MOFs in heavy metal ion detection are also discussed. This review highlights the potential of MOFs for the detection of heavy metal ions in water and provides a feasible approach for the development of efficient and sensitive sensors.
