Photocatalytically-active and photocontrollable coatings based on titania-loaded hybrid sol–gel films

The photocatalytically-active coatings were obtained by immobilizing titania nanoparticles into a sol-gel-derived SiO(x):ZrO(x) matrix. The resultant hybrid films show high photocatalytic, photobiocide and excellent corrosion protection properties which exhibit no degradation during the course of lo...

Description
Summary:The photocatalytically-active coatings were obtained by immobilizing titania nanoparticles into a sol-gel-derived SiO(x):ZrO(x) matrix. The resultant hybrid films show high photocatalytic, photobiocide and excellent corrosion protection properties which exhibit no degradation during the course of long-term irradiation with UV light. The possibility of a UV-induced opening of titania-based polyelectrolyte containers embedded into SiO(x):ZrO(x) film is also demonstrated that opens fresh opportunities in developing photocontrollable coatings capable to release encapsulated chemical agents under illumination.
