Single-site Ti-containing macroporous silica thin films with mesoporous frameworks were successfully prepared on quartz substrate with high transparency by using poly(methyl methacrylate) (PMMA) microspheres and organic surfactant as template of porous structures. The presence of mesoporous structure and the differences of macroporous structure of film surface were investigated by XRD and FE-SEM measurements. The local structure of Ti moieties embedded within silica matrixes were also confirmed by UV-vis investigations. It was found that the macroporous structure and the embedded single-site Ti moieties within mesoporous frameworks were quite effective for improvement of surface hydrophilicity, i.e., the water droplet was entirely spread on the film surface even before and after irradiation of UV light.
