Transparent thin layers of photocatalytic TiO2 were prepared using conventional sol-gel chemistry and a promising method of sol delivery to the substrate. Prepared sol based on tetraisopropoxy titanate and acetylacetone was loaded into a modified office inkjet printer equipped with piezoelectric print head. Sol was then printed onto pyrex glass plates, gelled at 110 degrees C and calcinated at 450 degrees C. Thus we prepared transparent thin layers of TiO2 of varying thickness and surface morphology. Structure of prepared layers was studied using optical microscopy, SEM and AFM. Layer thickness and crystalline phase structure were also determined. Photocatalytic performance was evaluated by the rate of DCIP decomposition and surface properties were studied by water droplet contact angle change. In this way we were able to prepare thin layers of TiO2 with excellent optical properties and photocatalytic performance comparable to dip- or spin-coated layers. Inkjet printing proved to be very elegant and clean method for sol deposition. Unlike the traditional methods of dip- and spin-coating, inkjet printing gives the user a great level of control over the deposition process, provides excellent efficiency of precursor use and easy scalability.
