ABSTRACT

Titania-supported gold catalysts calcined under vacuum have been studied using a combination of TEM and activity measurements for CO oxidation. A time dependent study by TEM suggested the presence of highly dispersed gold, a high percentage of which lies below the 1 nm resolution limit. A comparison between Au/TiO2 samples calcined in vacuum and air has shown large differences in catalytic behaviour, indicating that not only the size of gold particles but also the oxidized state of the support surface is important.
