Abstract

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

摘要

通过将ZIF-67负载到二维TiCT纳米片上制备了具有出色导电性的TiCT /ZIF-67纳米复合材料。TiCT片通过蚀刻TiAlC合成，然后ZIF-67在TiCT纳米片上生长。TiCT /ZIF-67纳米复合材料对葡萄糖表现出优异的检测性能，检测限低至3.81 μM，线性检测范围宽达5-7500 μM。这一出色的结果得益于TiCT的高导电能力和ZIF-67的活性催化性能的协同效应。此外，使用TiCT /ZIF-67纳米复合材料制备的电化学传感器在葡萄糖检测中也表现出优异的选择性、稳定性和重复性。具有出色性能的TiCT /ZIF-67纳米复合材料在电化学传感器方面具有潜在应用。
