Gas sensitivity of the nanostructured (FeSn)2O3 solid solutions

  • Jiang, Jianzhong (Project Manager)

Project Details


The gas-sensitive properties of nanostructured (FeSn)2O3 solid solutions prepared by high-energy ball milling have been investigated in atmospheres containing alcohol, CO, and CH4 gases. It has been found that materials show a high sensitivity with a short response time to the alcohol gas and almost no sensitivity to the other two gases, CO and CH4. Furthermore, it is found that the tin content in alpha-Fe2O3 and tin ions on the surface of alpha-Fe2O3 particles may play an important role in the enhancement of the gas sensitivity to the alcohol gas.
