摘要

研究了利用碳纳米管(CNTs)增强氧化锡(SnO2)气体传感器在室温下的传感性能。与单一材料传感器相比,碳纳米管/氧化锡混合传感器在室温下表现出优越的性能,特别是对氨气的高响应。利用传感器阵列进行气体分类测试,使用主成分分析和各种监督学习回归算法。结果表明,碳纳米管/氧化锡混合传感器显著优于碳纳米管传感器,具有更低的检出限和更高的分类精度,非常适合实际氨气监测应用。这些发现表明,碳纳米管/氧化锡混合传感器在各种环境中具有可靠和高效的气体监测潜力。

Enhanced Room Temperature Sensing Properties of Tin Oxide Gas Sensors Exploiting Carbon Nanotubes: High-Accuracy Ammonia Gas Classification via Supervised Learning Regression Algorithms.

The sensing properties of tin oxide (SnO2) gas sensors, enhanced by the exploitation of carbon nanotubes (CNTs), were explored at room temperature. The CNT/tin oxide hybrid sensors demonstrated superior performance at room temperature compared to single-material sensors, particularly, showing a high response to ammonia gas. A sensor array was utilized for gas classification tests using PCA and various supervised learning regression algorithms. Results indicated that the CNTs/tin oxide hybrid sensors significantly outperformed the CNT sensor, offering lower detection limits and higher classification accuracy, making them highly suitable for practical ammonia gas monitoring applications. These findings indicate the high potential of CNTs/tin oxide hybrid sensors for reliable and efficient gas monitoring in various environments.
