Colloidal Carbon Spheres and Their Core/Shell Structures with Noble‐Metal Nanoparticles

All wrapped up: Carbon-encapsulated metal nanoparticles, carbon microspheres decorated with metal nanoparticles, and particles with layered structures are all accessible by means of a method based on hydrothermal treatment of glucose, which produces monodisperse colloidal carbon microspheres with reactive surfaces. The picture shows silver-cored carbon spheres obtained by using silver nanoparticles as seeds.
