Fabrication of Micrometer-Scale Anatase-Phase TiO2 Congeries Assembled with Hollow Spheres
Abstract:Micrometer-scale anatase-phase TiO2 congeries assembled with hollow spheres have been synthesized by a bubble-template method combined with a facile chemical process. The as-prepared products were characterized by means of X-ray diffraction, field emission scanning electron microscopy, and transmission electron microscopy. Some of the congeries exhibited unique three-dimensional hierarchical architectures. The bubble-template strategy used in the synthetic process may represent a general approach to fabricate hollow micro- and nanostructures and therefore contribute to the formation mechanisms of hollow micro- and nanostructures.
