摘要
The copper benzene-1,3,5-tricarboxylate (Cu-BTC) with outstanding chemical and physical properties, is a novel and promising material in the field of electrochemical sensing. However, it has significant limitations for direct application in electrochemical sensing due to the relatively weak conductivity of Cu-BTC. Here, the conductivity of Cu-BTC was improved by loading Cu-BTC onto two-dimensional Ti3C2Tx nanosheets with high conductivity. Thanks to the synergistic effect produced by the high conductivity of Ti3C2Tx and the unique catalytic activity of Cu-BTC, the Ti3C2Tx/Cu-BTC nanocomposite exhibits excellent sensing performance for glyphosate, with a low limit of detection (LOD) of 2.6 × 10-14 M and wider linear sensing range of 1.0 × 10-13 to 1.0 × 10-6 M. Moreover, the electrochemical sensor based on Ti3C2Tx/Cu-BTC also shows excellent selectivity, good reproducibility and stability.
