Trattamenti a base di Tio2 nanocristallino ad azione protettiva indiretta fotocatalitica applicati ai Beni Architettonici

The research is focused on the definition of a diagnostic program to verify a protective product for stone surfaces. The objective is, in particular, to verify the treatments efficacy of nanocrystalline TiO2 (Titania) with indirect photocatalytic protective action, in the form of thin films made through the sol-gel method, and applied to the stone materials of the Monumental Heritage, through a poly-methodological scientific research, that allow to assess the innovative behaviour towards the fundamental principles of conservation and restoration of the architectural-artistic heritage. To define the research’s program have collaborated Department of Geosciences of University of Padova, ISTM-CNR Institute of Molecular Science and Technologies of Padova, MIUR research Laboratory “C.S.G. Palladio” of Vicenza, “Materiali Nanostrutturati s.r.l.” society of Sassuolo (MO), “Ecochem s.r.l.” society of Vicenza. The program provides verifications in laboratory and in-situ tests on certain Venetian monuments, to experiment the properties of indirect protecting action of nanocrystalline TiO2. The research’s purpose is to try and demonstrate that the application of these nanostructural products has the advantage of being compatible with the environment and coherent with the contemporary challenge of sustainable development of chemistry, of which the applied photochemistry technology could represent a winning solution.
