The sensitive determination of VB₂ has broad analytical applications. In this work, a novel VB₂ electrochemical sensor based on the 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, TEM analysis, cyclic voltammetry, differential pulse voltammetry, and electrochemical impedance spectroscopy. The sensor exhibited a high sensitivity of 0.05 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.

VB ₂的灵敏测定具有广泛的分析应用。在这项工作中，构造了一种基于水热法的新型VB ₂电化学传感器，以在电纺碳纤维表面上均匀生长二硫化钼和银纳米颗粒。通过扫描电子显微镜，EDS光谱，TEM分析，循环伏安法，差动脉冲伏安法和电化学阻抗谱对MoS ₂ -Ag-CNF进行了表征。该传感器表现出0.05至40μM的高灵敏度，响应时间快，检测限低至0.02μM。电极还显示出对各种干扰的出色选择性。这些结果表明，MoS ₂-Ag-CNF纳米复合材料可能是用于电化学生物传感的有前途的电极材料。
