Abstract

Ag nanoparticles (AgNPs) were prepared by a galvanic reaction between Ag+ ions and Co metal particles supported on carbon. Variation of the preparation conditions provided a series of AgNPs with various sizes (ca. 2–12 nm). By using the various AgNPs, the size effect on the oxygen reduction reaction activity was investigated. The mass activity of AgNPs increased with a decrease of the size. On the other hand, the Ag-surface-area-specific activity decreased with a decrease of the size.
