Platinum, palladium, and silver nanotubes of 6–7‐nm outer diameters are synthesized by the reduction of metal salts confined to lyotropic mixed‐surfactant liquid crystals (see picture). The lyotropic liquid crystals act as a template and are formed by the 1:1 combination of medium and large surfactant molecules into a hexagonal array of cylindrical rodlike micelles.
