Novel Pt–Co alloyed nanocatalysts are generated via chemical vapor deposition‐assisted facile one‐pot synthesis. The method guarantees highly monodisperse Pt–Co alloy nanoparticles with precise control of metallic compositions within 1 at%. A significant features is that a perfectly alloyed single‐crystal structure is obtained at temperatures as low as 500 °C, which is much lower than conventional alloying temperatures.
