Abstract

Using a modified depositionprecipitation procedure and a new reductive conditioning method, Au/TiO2 catalysts with small metallic Au particles (<2 nm) and a very high activity for low-temperature CO oxidation were prepared. The particles are stable during reaction; a decreasing activity is caused by the accumulation of by-products on the catalyst.
