| Outline of Final Research Achievements |
We synthesized visible-light-responsive TiO2 doped with metal ions (M-TiO2) for the photocatalytic degradation of gaseous acetaldehyde or 4-chlorophenol in water. Only Cr-, Pt-, and V-TiO2 showed photocatalytic activity for the degradation of gaseous acetaldehyde. These metal ion dopants existed with two or more valence states in TiO2. We also demonstrated that the Cr-TiO2 film prepared on a glass substrate can be used to degrade acetaldehyde under indoor LED. For water purification, V-TiO2 was coated on a hollow glass beads to float in water and used for the degradation of 4-chlorophenol.
