Highly ordered Pt nanodot arrays with cubic symmetry are synthesized by simple immersion of mesoporous silica thin films into a Pt precursor solution followed by photoreduction. Two types of cages of mesoporous thin films have been fully filled with Pt nanoparticles approximately 4 nm in size, and an exceptionally well‐ordered cubic lattice array of nanodots has been obtained (see figure).
