Fast Response Isopropanol Sensing Properties with Sintered BiFeO(3) Nanocrystals

BiFeO(3) nanocrystals were applied as the sensing material to isopropanol. The isopropanol sensor based on BiFeO(3) nanocrystals shows excellent gas-sensing properties at the optimum working temperature of 240 °C. The sensitivity of as-prepared sensor to 100 ppm isopropanol is 31 and its response an...

description BiFeO(3) nanocrystals were applied as the sensing material to isopropanol. The isopropanol sensor based on BiFeO(3) nanocrystals shows excellent gas-sensing properties at the optimum working temperature of 240 °C. The sensitivity of as-prepared sensor to 100 ppm isopropanol is 31 and its response and recovery time is as fast as 6 and 17 s. The logarithmic curves of the sensitivity and concentration of BiFeO(3) sensors are a very good linear in the low detection range of 2–100 ppm. In addition, the gas sensing mechanism is also discussed. The results suggest that the BiFeO(3) nanomaterial can be potentially applied in isopropanol gas detection.
