In this work, flower-like stannous sulfide (SnS) nanomaterials are synthesized using a hydrothermal method and used as sensitive materials for cataluminescence (CTL)-based detection of diethyl ether. Gas sensors based on SnS nanomaterials are prepared, and the SnS nanomaterials exhibit excellent gas-sensitive behavior towards ether. High sensitivity to ether is achieved at a relatively low operating temperature (153 °C) compared to other common sensors. The response time is 3 s and the recovery time is 8 s. The CTL intensity shows a good linear relationship (R = 0.9931) with a detection limit of 0.15 ppm and the concentration of ether in the range of 1.5-60 ppm. The proposed CTL sensor shows good selectivity towards ether. In addition, a highly stable signal is obtained with a relative standard deviation of 1.5%. This study indicates that the SnS-based sensor has excellent gas-sensitive performance and shows potential for applications in the detection of ether.
在本工作中，采用水热法合成了花状硫化亚锡（SnS）纳米材料，并将其用作基于催化发光（CTL）检测乙醚的敏感材料。制备了基于SnS纳米材料的气体传感器，该SnS纳米材料对乙醚表现出优异的气敏行为。与其他常见传感器相比，在相对较低的工作温度（153℃）下对乙醚具有高灵敏度。响应时间为3 s，恢复时间为8 s。CTL强度与乙醚浓度在1.5 - 60 ppm范围内呈现良好的线性关系（R = 0.9931），检测限为0.15 ppm。所提出的CTL传感器对乙醚具有良好的选择性。此外，获得了高度稳定的信号，相对标准偏差为1.5%。本研究表明，基于SnS的传感器具有优异的气敏性能，在乙醚检测中显示出应用潜力。
