Abstract
Transparent Ti‐containing mesoporous silica (TMS) thin films can be prepared on quartz plates using the spin‐coating sol‐gel method. These thin films have performed super‐hydrophilic surface property. Using a photo‐assisted deposition (PAD) method, nano‐sized Pt metal can be highly deposited on TMS thin films under UV‐light irradiation. XAFS measurement indicates that TMS thin films contain isolated and tetrahedrally coordinated Ti‐oxide moieties in the frameworks and nano‐sized Pt particles can be highly deposited on the photo‐excited Ti species in TMS thin films. Measurement of contact angle of droplet water showed that the surface property of Pt/TMS thin film is also hydrophilic as comparable to that of original TMS thin film.
