Communication-Pseudohalide Beta-Cuscn Nanorod-Based Thin Film As A Potential Hydrogen Gas Sensor

We introduced a new insight into using pseudohalide CuSCN in hydrogen gas sensors. A sensor device with an electrodeposited p-type beta-CuSCN nanorod thin film as an active layer was used to obtain effective gas sensing. Densely distributed nanorods as a medium of charge transfer exhibited an excellent sensor response towards H-2, with fast response and recovery rates of 6 s and 7 s, respectively. Further, the stability of the device is noteworthy. A 500% response percentage was achieved with 100 ppm H-2, which was very high. This work can significantly improve the use of pseudohalides in the field of gas sensors. (c) 2020 The Electrochemical Society ("ECS"). Published on behalf of ECS by IOP Publishing Limited.
