摘要：

The effects of H+/Ti molar ratio on the formation of mesoporous structure and the phase transition have been investigated, and the mesoporous titania with bicrystalline framework consisting of anatase and rutile was characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), BET surface area, and BJH pore size distribution.
