Porous metallic replicas of colloidal silica crystals have been produced by filling the spaces between the silica spheres with aqueous solutions containing salts of either Pt or Au. Subsequent reduction to the metal and removal of the template gave rise to a faithful replication of the porous structure for Pt (the Figure shows an edge) while the porous gold showed some disorder.
