Aging of the photocatalytic TiO2 thin films modified by Ag and Pt

- Photocatalytic TiO2 coatings were treated by Ag or Pt.
- Aging was observed by SEM and XPS.
- Photocatalytical efficiency was measured by AO7 decomposition.
- Pt treatment is more effective considering 16 months aging.
- Nitrogen presence was detected in case of Pt treatment.
