In this work, we focus on the outdoor testing of transparent, photocatalytically-active, TiO2 layers obtained by ink-jet printing of aqueous, nanoparticle containing sols. This approach includes a thermal treatment at strongly reduced temperatures (150 to 500 degrees C), still resulting in coatings with photocatalytic properties comparable to, or in some cases even better than, commercially available, physical deposition based or conventional sol-gel deposited films. This type of titania coatings is being used in outdoor conditions for self-cleaning and antibacterial coatings. This means that they need to exhibit good durability and long term performance. Yet, reducing the thermal treatment temperature might have a negative effect on these parameters. This paper presents simulated artificial weathering, antibacterial and corrosion tests on the processed films, making it possible to assess their performance under real life conditions.
