Research on Sensing of H₂S Based on Cu₂O/CNF Heterostructures

摘要: 本研究报道了一种基于Cu₂O/CNF (碳纳米纤维)异质结构研发的超灵敏H₂S气体传感器。Cu₂O/CNF异质结构通过二维电化学原位沉积法制备。通过对该传感器的表征，发现该异质结构具有较大的比表面积和清晰的异质界面，这有助于提高传感器的灵敏度和响应速度。实验结果表明，该传感器对H₂S气体表现出极高的灵敏度，响应时间短，可靠性高。该研究为设计和制备高效的H₂S气体传感器提供了新思路，并有望应用于环境监测和工业安全等领域。

Abstract: An ultra-sensitive H₂S gas sensor based on Cu₂O/CNF (carbon nanofibers) heterostructures is reported in this paper. Cu₂O/CNF heterostructures were prepared by two-dimensional electrochemical in-situ deposition. Through the characterization of the sensor, it is found that the heterostructure has a large specific surface area and a clear heterogeneous interface, which is helpful to improve the sensitivity and response speed of the sensor. The experimental results show that the sensor has a high sensitivity to H₂S gas, short response time and high reliability. This study provides a new idea for the design and preparation of efficient H₂S gas sensors, and is expected to be applied to environmental monitoring and industrial safety.
