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.

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.
