Preparation of mesoporous silica-titania transparent composite thin film

Abstract

Transparent mesoporous silica thin films were successfully prepared on glass substrates by spin coating method. The precursory solution were prepared by hydrolysis of tetraetylorthosilicate (TEOS) and titanium tetoraisopropoxide in the presence of cetyltrimethylammonium bromide (CTAB) as the template at room temperature. Transparent mesoporous silica-titania thin films were successfully prepared on glass substrates by spin coating method. The content of titania was a maximum of 20wt% to silica.
