Growing small silver particle as redox catalyst

Research was conducted to examine the catalytic properties of growing small silver particle. The silver clusters were prepared by the reduction of silver ions in the presence of an electron acceptor dye. It was observed that the silver particles were more efficient catalysts than stable coloidal particles. The catalytic characteristic of the particles is attributable to efficient particle-mediated electron transfer from the BH4- ion to the dye and depends on their size and the dye-particle interaction.
