Hydrophilicity and Photocatalytic Activity of TiO2 Thin Films Coating on Glass |
| 초록 |
TiO2 could apply self-cleaning fields as well as photocatalytic reaction to decompose toxic organic compounds because of photocatalytic and hydrophilic materials. For the photocatalytic mechanism, it has been known that the photogenerated electrons and holes react with O2 and H2O in air and produce the active oxygen species (•O2- and •OH) with strong oxidation power. They attack toxic and harmful organic compounds for their decomposition. On the other hand, the hydrophilicity of TiO2 is related with the interficial property. When TiO2 was irradiated under UV light, its interficial composition was changed and it allows water to spread completely across the surface without remaining the droplets. The interesting point is that the photocatalytic reaction and hydrophilicity of TiO2 take place simultaneously on its surface. Some groups investigated the relationship between the activity and hydrophilicity of photocatalyst for self cleaning. In our work, we investigated the photocatalytic activity and hydrophilicity of TiO2 film coated on glass with three different TiO2 sols by spin coating method and compared those of the calcined and uncalcined TiO2 thin films. |
