Hybrid Au/Ag nanorods (NRs) are synthesized by initiating secondary growth on premade Au NRs stabilized with tightly binding binary surfactants. By utilizing long, thin Au NRs and carefully manipulating the reduction conditions, Au/Ag hybrid nanostructures are achieved either in the form of Ag‐capped tips or as a uniform overgrowth of Ag.
