Abstract

We introduced a new insight into using pseudohalide CuSCN in hydrogen gas sensors. A sensor device with an electrodeposited p-type β-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 H2, 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 H2, which was very high. This work can significantly improve the use of pseudohalides in the field of gas sensors.
