MXene-Cu2O复合材料室温下检测NO2气体性能的研究
|
Abstract:
针对传统NO2检测技术依赖高温、灵敏度不足等问题，本研究通过水热法制备了MXene-Cu2O复合材料，开发了一种新型室温下超灵敏气体传感器。实验表明，传感器在室温下展现出宽线性检测范围、低检测限及优异抗干扰性，可稳定检测ppb至ppm级NO2。该研究为开发低功耗、高灵敏的室温气体传感器提供了新策略，在环境监测与工业安全领域具有重要应用价值。
To address the limitations of conventional NO2 detection technologies, such as high-temperature operation and insufficient sensitivity, this study developed a novel room-temperature ultrasensitive gas sensor based on MXene-Cu2O composites synthesized via a hydrothermal method. Experimental results demonstrate that the sensor exhibits a wide linear detection range, low detection limit, and excellent anti-interference capability, enabling stable detection of NO2 from ppb to ppm levels at room temperature. This research provides a new strategy for designing low-power, high-sensitivity room-temperature gas sensors, offering significant application potential in environmental monitoring and industrial safety fields.
