Layered treatments of natural stones based on dispersions of experimental nano-TiO2 and commercial TEOS showing photocatalytic and self-cleaning properties were set up and tested. To enhance nano-TiO2 efficacy, a surface pre-treatment with tetraethyl orthosilicate was proposed to avoid the penetration of NPs into the crystalline porous substrates and to… CONTINUE READING
