Abstract

The fast detection of hazardous gases such as methane (CH4) enhances the safety and protection of concerned industries, mining and residential areas. The sensors used forthe gas detection should have very high sensitivity, fast response time (TS) and recovery time (TR). In this work, tin dioxide(SnO2) nano-particles have been synthesized by precipitation and simultaneous sonication techniques. Its methane (CH4) gas sensing capability is noticeably better than the tin dioxide(SnO2) based gas sensor prepared conventionally. Further, palladium (Pd) incorporation in pure tin dioxide (SnO2)enhances its catalytic motion and antimony (Sb) doping reduces sensor resistance in Kilo-ohm range. Thus, a combined Pd–Sbdoped SnO2 gas sensor exhibits approximately 98% sensitivity to CH4 at modest operating temperature with fast response and recovery times. These results establish the Pd-incorporated, Sbdoped SnO2 gas sensor as a strong and reliable candidate for efficient detection of combustible CH4 gas.
