Secondary building blocks within the cavities of primary silica‐architecture building blocks are successfully engineered. The immobilized surfactant directs the selective dissolution and reassembly of dissolved silicate species for the formation of secondary building blocks (hollow nanospheres/nanorods; see figure). Supported TiO 2 on nanostructures with multilevel interiors is shown to exhibit significantly enhanced activity in photocatalytic H 2 production.
