H2S sensing properties of SnO2-based sensor promoted with MoO3 |
| 초록 |
H2S is a colorless toxic gas that is considered immediately dangerous to human’s life and health even at low concentration. Also, H2S generates SO2, causing fine dust through a photocatalystic reaction in atmosphere. Due to these hazards, a sensor capable of detecting low concentrations of H2S is required. So, in this study, we fabricated SnO2-based thin film semiconductor gas sensors for H2S detection using ion sputter. The SnO2-based thin film gas sensor shows high values of 93% response and 94% recovery for H2S 1ppm at 350oC, but did not show complete recovery. For complete recovery, we added Mo on SnO2 thin film. As a result, the SnO2 based thin film sensor promoted with MoO3 shows response of 90% and recovery of 100% for 1ppm H3S at 350oC. |
