Abstract

Among the various metal oxide additives tested, Ag₂O is outstanding in promoting the sensing properties of γ-Fe₂O₃ element to H₂ in air. The γ-Fe₂O₃ element loaded with 6 wt.% Ag₂O is very sensitive to H₂ at 320 °C, while it is also sensitive to many other gases, especially C₂H₅OH. The element is highly sensitive and selective to H₂ and LPG, after it is modified with the surface-coat of Al₂O₃ containing 1.5 wt.% PtO. The response of this element to H₂ and C₄H₁₀ is rather rapid (only 4 and 6 s, respectively), and its resistance only changes 8.9% even when the ambient relative humidity varies broadly (from 10 to 98%). So the element is very useful to detect the leakage of coal gas or LPG in domestic appliances.
