Abstract
MXenes, as recently emerging lamellar two-dimensional (2D) materials of transition metal carbides and/or nitrides, have attracted intensive attention for various applications in sensors, catalysis, energy storage, and biomedicine owing to their fascinating and technologically useful properties. This review presents the current progress of MXene-based materials applied in the field of electrochemical sensors. Firstly, how synthetic strategies and surface modification affect the properties of MXene was emphasized. Secondly, MXene as an electrode material for constructing electrochemical sensors based on MXene nanocomposites, especially metal nanoparticles (MNPs)/MXene, conductive polymers (CPs)/MXene, and carbon materials/MXene nanocomposites, was well discussed. Finally, the challenges and outlooks in this field with possible solutions and future opportunities are discussed.
