Since the discovery of ordered mesoporous silica materials (e.g. MCM-41) in early 1990s [1, 2, 3], they have attracted considerable attention due to their high specific surface area and possible applications as adsorbent, catalyst, optical materials, sensors, and separatory materials [3, 4, 5]. A wide range of mesoporous silica materials have been prepared using the structure-directing functions of electrostatic, hydrogen-bonding, and van der Waals interactions. Recently, many efforts have been taken to synthesize ordered mesoporous transition metal oxides for their enormous potential that is not possessed by silica in the fields of electromagnetic, photoelectronics, catalysis, etc. [6, 7, 8].
Titanium dioxide (TiO2) is a really interesting material because of its numerous applications, for example, photocatalysis and catalyst support. There are eight polymorphs of titania . Among them, only anatase and rutile are practical applications, because they are stable under...
