Abstract The nature of electronic interaction between noble metal and semiconducting oxide was investigated for Pd-loaded SnO{sub 2} sensor elements. It was shown that SnO{sub 2} grains contacting to PdO were strongly depleted of electrons in air. This electronic interaction disappears on exposure not only to H{sub 2}-containing air but also to He (inert gas). On the basis of these results, it was suggested that the adsorbed oxygen formed at the PdO-SnO{sub 2} interface is responsible for the electronic interaction.
