Abstract

A recoverable SnO₂-based gas sensor, promoted simultaneously with three components such as Mo, Sb, and Ni (Mo5Sb1·Ni(I)), was developed in this study for the detection of DMMP. The Mo5Sb1·Ni(I) sensor showed not only excellent sensor response in the detection of a very low concentration of DMMP (ppb level) in a flow system, but also complete recovery. In particular, the Mo5Sb1·Ni₂(I) sensor developed in this study showed a high sensor response of about 70% in the detection of 0.5 ppm DMMP at 350 °C, and the sensor response was maintained during multiple cycles of detection and recovery. Moreover, the sensor showed the sensor response of 42% in the detection of even very low concentrations of DMMP of 0.1 ppm. These results were due to the effects of promoters such as Mo, Sb, and Ni. Mo and Sb promoters play an important role in the improvement of the recovery ability of sensor, and Ni promoter plays an important catalytic role in the enhancement of the response level of sensors.
