摘要：

二甲苯是工业生产中关键的化工原料，可用于生产油墨、涂料等，是一种典型的挥发性有机化合物。作为燃料、油漆的常用稀释剂，工业生产的常用溶剂，生活及生产过程中都避免不了与二甲苯进行接触。这种典型的挥发性有机化合物含量一旦接触超标就会对人类的身体健康造成威胁，因此二甲苯气体的检测很有必要。目前，许多金属氧化物半导体和碳材料都被认为是有潜力的气体传感材料，但是由于对传感器的性能要求会不断提高，研究新型的气体传感材料尤为重要。碳材料如石墨烯、碳纳米材料出现后，为敏感材料的研发开辟了新的方向。本文采用水热反应法成功合成出了荧光碳纳米材料复合的NiO，并研究了材料的传感性能。结果表明材料对二甲苯具有良好的响应，紫外光激发及最佳工作温度条件下对1.3μL/L二甲苯灵敏度可以达到2.9，检测下限可以达到0.215μL/L，对SO₂、丙酮、甲苯、甲醛等干扰气体具有选择性，响应时间29s，恢复时间31s。

Abstract:

Xylene is a key chemical raw material in industrial production and can be used to produce inks and coatings. It is a typical volatile organic compound. As a common diluent for fuel and paint and a common solvent for industrial production, contact with xylene is inevitable in life and production. Once the content of this typical volatile organic compound exceeds the standard, it will pose a threat to human health. Therefore, the detection of xylene gas is necessary. At present, many metal oxide semiconductors and carbon materials are considered as potential gas sensing materials, but because the performance requirements of the sensors will continue to increase, it is particularly important to study new gas sensing materials. The emergence of carbon materials such as graphene and carbon nanomaterials has opened up new directions for the development of sensitive materials. In this paper, the method of hydrothermal reaction was used to successfully synthesize the NiO composite of fluorescent carbon nanomaterials, and the sensing properties of the materials were studied. The results showed that the material had a good response to xylene. The sensitivity to 1.3μL/L xylene can reach 2.9 under ultraviolet excitation and optimal working temperature, and the detection limit can reach 0.215μL/L. The interference gas was selective with a response time of 29s and a recovery time of 31s.
