摘要：

Ti-containing mesoporous silica thin films (Ti-MSTFs) have been prepared on Al and Al-Mg alloy substrates via a sol-gel/spin-coating method including two different processes for removal of a structure directing agent (SDA). One is calcination and the other is photocatalytic removal under UV-light irradiation utilizing photocatalysis of tetrahedrally coordinated titanium oxide moieties within the silica framework. Characterizations of mesoporous structures and local structures of titanium oxide moieties were performed by FT-IR, XRD, and UV-vis measurements. Water contact angle measurements revealed that highly hydrophilic surfaces were successfully formed on both metallic substrates by coating with Ti-MSTFs. These surfaces also exhibited photoinduced superhydrophilic properties under UV-light irradiation. (C) 2010 Elsevier B.V. All rights reserved.
