A Ti3C2Tx/ZIF-67 nanocomposite with outstanding conductivity has been prepared by loading ZIF-67 onto a two-dimensional Ti3C2Tx nanosheet. Ti3C2Tx sheets were synthesized by etching Ti3AlC2, and then ZIF-67 was grown in situ on the Ti3C2Tx nanosheet. The Ti3C2Tx/ZIF-67 nanocomposite exhibits excellent detection performance for glucose, with a low LOD of 3.81 μM and wide linear detection range of 5–7500 μM. This terrific result is contributed by the synergistic effect of the high electrically conductive ability of Ti3C2Tx and active catalytic performance of ZIF-67. Moreover, the electrochemical sensor prepared using the Ti3C2Tx/ZIF-67 nanocomposite also shows excellent selectivity, stability and repeatability for glucose detection. The Ti3C2Tx/ZIF-67 nanocomposite with outstanding performance has potential applications for electrochemical sensors.
