Synthesis of nanomaterials using cheap and highly efficient material is an important aspect of nanotechnology. In this present work, we have used the carbon black (CB) as a highly conductive and inexpensive carbonaceous material for the fabrication of the electrochemical sensor. However, the poor dispersion in water obstructs the usage of CB in electrochemical sensor and biosensor applications. Hence, the CB was functionalized by simple reflux method and the functionalized CB (f‐CB) nanospheres hybrids with hydrothermally synthesized MoS₂ nanoclusters by simple ultrasonication process. In addition, the various suitable spectrometric techniques used to probe the surface morphology and chemical modification of the prepared materials. The prepared MoS₂ and f‐CB nanohybrids (f‐CB/MoS₂) applied for the electrocatalytic reduction of toxic chloramphenicol (CAP). Fascinatingly, the f‐CB/MoS₂ modified electrode showed a competitive electrocatalytic performance comparing with other modified electrodes. At the optimized condition, the sensor exhibited the LOD about 0.002 μM, wider linear range 0.015 to 1370 μM with the sensitivity of 3400 μA μM⁻¹ cm⁻² for the determination of CAP. Moreover, the practical viability of the sensor was exploited in milk powder and honey samples.

功能化的炭黑纳米球与MoS2纳米团簇混合，可有效电催化氯霉素的还原

使用廉价且高效的材料合成纳米材料是纳米技术的重要方面。在本工作中，我们已经使用炭黑（CB）作为高导电性和廉价的碳质材料来制造电化学传感器。然而，在水中的不良分散阻碍了CB在电化学传感器和生物传感器应用中的使用。因此，通过简单的回流方法将CB功能化，并通过简单的超声处理功能化功能化的CB（f-CB）纳米球与水热合成的MoS ₂纳米团簇混合。另外，用于探测所制备材料的表面形态和化学改性的各种合适的光谱技术。准备好的MoS ₂和f‐CB纳米杂化物（f‐CB / MoS₂）用于电催化还原有毒氯霉素（CAP）。令人着迷的是，与其他修饰电极相比，f-CB / MoS ₂修饰电极显示出竞争性的电催化性能。在最佳条件下，传感器的LOD约为0.002μM，线性范围为0.015至1370μM，对CAP的测定灵敏度为3400μAμM ^-1  cm ^-2。此外，在奶粉和蜂蜜样品中还利用了传感器的实际可行性。
