A size‐dependent catalytic activity : The hydrogenation of anthracene in aqueous micellar solutions at room temperature is catalyzed by ionic‐surfactant‐protected gold nanoparticles with well‐controlled particle sizes (see picture). The size‐dependent catalysis of Au nanoparticles on the hydrogenation shows an optimal activity at particle sizes of 3 to 5 nm.
