Synthesis and photocatalytic activity of mesoporous titania with wormhole-like framework structure consisted of TiO2(B)

摘要

Since the discovery of ordered mesoporous silica materials(e.g. MCM-41) in early 1990s [1–3], they have attracted considerable ttention due to their high specific surface area and possible applications as adsorbent, catalyst, optical materials, sensors, and separatory aterials [3–5]. 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 fforts 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.[6–8]
