Yolk–shell photocatalysts: We have developed an efficient method for making highly monodisperse yolk–shell microspheres using core–shell silica as a template. SiO2-TiO2 microspheres show enhanced photocatalytic activity, presumably as a result of multiple reflections of light within the interior cavities. This core–shell template method is effective for the synthesis of other yolk–shell microspheres with different metal oxides.
