ABSTRACT
A Ti3C2T x /ZIF-67 nanocomposite with outstanding conductivity has been prepared by loading ZIF-67 onto a two-dimensional Ti3C2T x nanosheet. Ti3C2T x sheets were synthesized by etching Ti3AlC2, and then ZIF-67 was grown in situ on the Ti3C2T x nanosheet. The Ti3C2T x /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 Ti3C2T x and active catalytic performance of ZIF-67. Moreover, the electrochemical sensor prepared using the Ti3C2T x /ZIF-67 nanocomposite also shows excellent selectivity, stability and repeatability for glucose detection. The Ti3C2T x /ZIF-67 nanocomposite with outstanding performance has potential applications for electrochemical sensors.
