Abstract

original image

The synthesis within: Highly monodisperse core–shell nanoparticles (SiO2/TiO2, SiO2/ZrO2) with a polydispersity index of <1.01 and a diameter of 3 nm were synthesized within structurally exact self-assembled spherical Pd complexes that act as three-dimensional templates (see picture; gray spheres: TiO2 or ZrO2, purple spheres: SiO2, yellow spheres: Pd).
