| Abstract: | The research on ethanol-sensing materials, such as SnO_2, ZnO, Fe_2O_3 and composite metal oxide was
summarized. The effects of dopant and nanosization of partical size were discussed. The newest developed 8 nm In_2O_3-based
ethanol-sensing material was prepared by microemulsion method and doped with small amount of Pt and La_2O_3. The ethanol
sensors made from above-mentioned material have low power consumption (<150 mW), high sensitivity, selectivity, and long
term stability. The response time was 7s and recovery time 30s. The ethanol-sensing mechanism was also analyzed. |
