| Summary: | In this paper, composite nanostructures are constructed successfully by combining conductive carbon-based materials with MoS2. The MoS2/reduced Graphene Oxide (rGO) composite was synthesized by hydrothermal method, and its morphology, elemental composition and microstructure were characterized in detail. Then, the MoS2/rGO composite material was modified on the glass carbon electrode (GCE) to construct the methyl parathion (MP) electrochemical sensor. The experimental results show that compared with a single MoS2/GCE modified electrode, the MoS2/rGO modified electrode exhibits significantly improved electrochemical performance. This boost can be attributed to the rGO’s high electrical conductivity and its good interface combination with MoS2, which work together to facilitate electron transport and enhance catalytic activity. In the electrochemical detection of MP, the MoS2/rGO modified electrode shows excellent sensitivity, and its detection limit of MP reaches 11.92 ng/mL, providing an effective solution for the detection of MP with high sensitivity. |
