Abstract

Unique nanostructures contribute to optimizing gas-sensitive properties, which has been widely acknowledged in the field of gas sensing. However, the construction of nanostructures by the in situ method is still challenging. In this work, nanorod-assembled SnWO₄ was fabricated directly on interdigital electrodes by a one-step aerosol-assisted chemical vapor deposition method. The xylene gas sensor was developed, featuring low detection limits and fast response. Under the operating temperature of 350°C, the detection limit of the SnWO₄ sensor for xylene reaches a minimal level of 10 ppb. Meanwhile, the sensor exhibits excellent performance in response time, providing a rapid response of 2 s to 100 ppm xylene. Apart from this, the sensor also exhibits good selectivity. Among various volatile organic compound gases of the same 100 ppm at 350°C, the sensor’s response to xylene (484%) is 3.6 times that of toluene and 5.3 times that of benzene. The excellent gas-sensing performance is primarily due to the unique structural properties of nanorod-assembled SnWO₄. This paper holds significant research potential in the field of gas sensing, particularly for the development of high-performance xylene sensors.

AACVD法原位生长ppb级二甲苯气体传感器用纳米棒组装的snowo4

独特的纳米结构有助于优化气敏性能，这在气敏领域得到了广泛的认可。然而，用原位方法构建纳米结构仍然具有挑战性。在这项工作中，采用一步气溶胶辅助化学气相沉积方法直接在数字电极上制备了纳米棒组装的SnWO4。研制了检测限低、响应速度快的二甲苯气体传感器。在350°C的工作温度下，SnWO4传感器对二甲苯的检测极限达到最低水平10 ppb。同时，传感器在响应时间上表现出优异的性能，提供2秒到100 ppm二甲苯的快速响应。此外，该传感器还具有良好的选择性。在350°C下，在相同100 ppm的各种挥发性有机化合物气体中，传感器对二甲苯（484%）的响应是甲苯的3.6倍，是苯的5.3倍。优异的气敏性能主要是由于纳米棒组装的SnWO4的独特结构特性。本文在气体传感领域，特别是高性能二甲苯传感器的开发方面具有重要的研究潜力。图形抽象

期刊介绍： The Journal of Electronic Materials (JEM) reports monthly on the science and technology of electronic materials, while examining new applications for semiconductors, magnetic alloys, dielectrics, nanoscale materials, and photonic materials. The journal welcomes articles on methods for preparing and evaluating the chemical, physical, electronic, and optical properties of these materials. Specific areas of interest are materials for state-of-the-art transistors, nanotechnology, electronic packaging, detectors, emitters, metallization, superconductivity, and energy applications. Review papers on current topics enable individuals in the field of electronics to keep abreast of activities in areas peripheral to their own. JEM also selects papers from conferences such as the Electronic Materials Conference, the U.S. Workshop on the Physics and Chemistry of II-VI Materials, and the International Conference on Thermoelectrics. It benefits both specialists and non-specialists in the electronic materials field. A journal of The Minerals, Metals & Materials Society.
