摘要：
Rare earth ferrite-DyFeO(3)powders with variable particle sizes and surface areas were prepared by the sol-gel method with annealing at 600 degrees C, 700 degrees C, 800 degrees C, and 900 degrees C to research the acetone sensing properties. The DyFeO(3)powders annealed at 800 degrees C showed a good response to acetone and can be used as an acetone sensor due to its excellent microstructure. Moreover, the best response of 3.81 for the DyFeO(3)sensor was observed at the operating temperature of 190 degrees C in 2 ppm acetone atmosphere. The response and recovery time were 42 s and 44 s, respectively, indicating that the DyFeO(3)material annealed at 800 degrees C can be used as a reusable acetone sensor. In addition, the DyFeO(3)material has excellent selectivity to acetone compared with 2 ppm other gases (ammonia, methanol, formaldehyde, ethanol and acetylacetone), suggesting that the application of DyFeO(3)material in acetone sensors is promising.
