Abstract

It is shown that the doping of Zn and Sn can improve the gas sensitivity of α-Fe₂O₃-based sensing material to CO. X-ray photo-electron spectroscopy analysis suggests that this is mainly due to the fact that the simultaneous doping of Zn and Sn can increase the S and hence SO^2-₄ contents in the α-Fe₂O₃(SO^2-₄, Sn, Zn) sensing material. The results also suggest that under a given condition, the gas sensitivity of α-Fe₂O₃(SO^2-₄, Sn, Zn) to CO can be optimised by properly adjusting the doped Zn content.
