This study present a new method to synthesize mesostructured titania, with a well-ordered hexagonal structure and a spherical morphology by the optimization of surfactant-templating cooperative assembly and re-dissolution in ethanol. The synthesized ordered mesostructured titania spheres (denoted as OMTS) were characterized with small-angle X-ray diffraction (SA-XRD), scanning electron microscope (SEM), and transmission electron microscope (TEM). We found that the OMTS adopt a spherical morphology (diameter of around 1 £gm) and well-ordered two-dimensional hexagonal structure. In addition, this method allows the introduction of other metal oxide species (such as Al or Zr) into the OMTS, which can potentially enhance the catalytic reactions. ?
