Construction of an electrochemical sensor for the detection of methyl parathion with three-dimensional graphdiyne-carbon nanotubes
To enhance the application performance of graphdiyne (GDY) in electrochemical sensing, carbon nanotubes (CNTs) were grown in situ to construct three-dimensional nanoarchitectures of GDY-CNTs composites. GDY-CNTs showed superior electrochemical properties and detection response to MP when compared with GDY, as the in situ growth of CNTs significantly increased the electrode surface area and enhanced the electron transfer process. GDY-CNTs were successfully used to construct electrochemical sensors for methyl parathion (MP). The proposed sensor exhibited a wide linear relationship for MP ranging from 0.09 to 64.6 µM with a detection limit of 0.05 µM. Moreover, the sensor also showed good stability and acceptable reproducibility, which provided a feasible method for rapid and accurate detection of MP in real samples. This work provides an effective application of graphdiyne in electrochemical sensing with constructed three-dimensional GDY-CNTs.
