Abstract

The most common tasks, we encounter during restoration stone historical monument buildings, include mainly cleaning and removing of the crust from their surface. As part of the experimental research of nanomaterials and the widespread use of these materials for the preservation and restoration of stone monuments, the use of TiO2 is currently being addressed. Applications have shown that this oxide can be used to protect against microorganisms and UV degradation due to its antifungal and antibacterial effects. At the same time, the photocatalytic properties of TiO2 represent the possibility of chemical decomposition and the creation of a self-cleaning environment and self-sterilization area. Applying lime nanosuspensions with TiO2 nanoparticles will reduce the rate of deposition of pollutants as a result of photocatalytic phenomena and thus slow the development of degradation processes.

Keywords: lime nanosuspension, TiO2, titanium dioxide, self-cleaning surfaces, stone crust, historical material
