摘要：

The effects of metal additives on the trimethylamine (TMA)-sensing properties of TiO2 have been investigated. The sensitivity to TMA is enhanced by the addition of 0.5 wt.% Ru, 2.0 wt.% In or 0.5 wt.% Au, whereas the addition of 0.5 wt.% Pt, 1.5 wt.% Pd or 1.5 wt.% Rh results in a decrease in the sensitivity. It is also revealed that the effect of each metal varies with the amount added. From the variations in resistance both in air and in 300 ppm TMA with the added amount of each metal, the roles of the metal additives are discussed.
