Abstract

The enwrapped 2D nanostructures on conductive flexible interfaces opened up new avenues to accelerate reaction kinetics for the development of highly sensitive electrochemical sensors. Herein, we report the direct growth of molybdenum disulfide nanosheets (MoS2NS) on carbon cloth (CC) as host interface via hydrothermal treatment. The as-prepared electrodes were then characterized by scanning electron microscope (SEM), atomic force microscope (AFM) and Raman spectroscopy. The designed MOS2 enwrapped interface demonstrated excellent electrochemical properties because of larger active surface area, good conductivity, and high porosity that led to large faradic current for dopamine (DA) oxidation. Meanwhile, the designed interface showed higher stability owing to good interactions in MOS2/CC interface with lower detection limit (0.3 µM), higher sensitivity (0.77 µA.µM−1 cm−2) in wider linear range of 250–4000 µM with considerable selectivity and good reproducibility.
