There has been increasing interest in the use of molybdenum disulfide (MoS₂) for the synthesis and application of functional hybrid nanomaterials. Here, for the first time, we prepared MoS₂ nanosheets that were modified with organic copper (OCu) nanowires by a facile two-step hydrothermal synthesis. Multi-characterization techniques such as scanning electron microscopy, transmission electron microscopy, and atomic force microscopy were used to observe the conjugation of OCu with MoS₂ and the morphology of the fabricated MoS₂–OCu nanohybrids. In addition, other methods such as X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction were utilized to understand the structure and properties of the prepared MoS₂–OCu nanohybrids. Finally, the synthesized MoS₂–OCu nanohybrids were further utilized to fabricate multi-functional electrochemical sensors for highly sensitive detection of hydrogen peroxide (H₂O₂) and ascorbic acid (AA). The obtained results indicate that the synthesized novel MoS₂–OCu nanohybrids exhibit excellent electrocatalytic activity towards both analytes, and present potential applications for detecting H₂O₂ and AA with high stability, sensitivity, and selectivity.

基于新型二维纳米杂化物的电化学传感器：与有机铜纳米线结合的MoS ₂纳米片，用于同时检测过氧化氢和抗坏血酸

人们对使用二硫化钼（MoS ₂）合成和应用功能性杂化纳米材料的兴趣日益增加。在这里，我们首次制备了MoS ₂纳米片，该纳米片由有机铜（OCu）纳米线通过简便的两步水热合成进行了改性。多表征技术如扫描电子显微镜，透射电子显微镜和原子力显微镜被用来观察OCU的与硫化钼的共轭₂和所制造的MoS的形态₂–OCu纳米杂化物。此外，还利用其他方法（例如X射线光电子能谱，傅里叶变换红外光谱和X射线衍射）来了解所制备的MoS ₂ -OCu纳米杂化物的结构和性能。最后，合成的MoS ₂ -OCu纳米杂合物被进一步用于制造多功能电化学传感器，用于高灵敏度检测过氧化氢（H ₂ O ₂）和抗坏血酸（AA）。所得结果表明，合成的新型MoS ₂ -OCu纳米杂化物对两种分析物均表现出优异的电催化活性，并在检测H ₂ O _2方面具有潜在的应用前景。以及具有高稳定性，灵敏度和选择性的AA。
