Nanosized Au core /Pt shell bimetallic particles are formed on the surface of TiO 2 in a highly dispersed state in a two‐step method utilizing its photocatalytic activity. The adsorptivity of sulfur‐containing compounds on the metal clusters can be finely controlled over a wide range by changing the Au/Pt atomic ratio. The picture shows a high‐resolution transmission electron micrograph of a single nanoparticle.
