A Highly Sensitive Electrochemical Sensor Based on Nanoflower-like MoS2-Ag-CNF Nanocomposites for Detection of VB2

Abstract

The sensitive determination of VB2 has broad analytical applications. In this work, a novel VB2 electrochemical sensor based on hydrothermal method was constructed to uniformly grow molybdenum disulfide and silver nanoparticles on the surface of electrospun carbon fiber. MoS2-Ag-CNF was characterized by scanning electron microscope, EDS spectrum, cyclic voltammetry, differential pulse voltammetry and electrochemical impedance spectroscopy. The sensor exhibited a high sensitivity of 0.05 μΜ to 40 μΜ with a fast response time and a low detection limit of 0.02 μM. The electrode also showed outstanding selectivity toward various interferences. These results indicate that the MoS2-Ag-CNF nanocomposites may be promising electrode materials for electrochemical biosensing.
