Abstract
The unique size-dependent chemical-physical properties of semiconductor nanocrystals can be profitably applied to the field of cultural heritage protection. The present paper accounts for the realization of colloidal TiO2 nanocrystals based coatings, with controlled morphology, with the goal to convey new functional properties to the surfaces of monuments and buildings of cultural interest. In the present paper, we collected the chemical-physical characterization and the investigation of the photocatalytic activity of rod-like TiO2 nanocrystals (TiO2NRs) based coatings applied to the Pietra Leccese, a porous calcarenite stone, extensively used in Southern Italy monuments. The application of TiO2 NRs based coatings was realized by three different techniques: casting, dipping and spray-coating. The coating resulted in a functional protective layer, with self-cleaning characteristics, as demonstrated by its photocatalytic activity, enabling a new generation of smart coatings.
