Abstract

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 TiO2 on nanostructures with multilevel interiors is shown to exhibit significantly enhanced activity in photocatalytic H2 production.
