The photocatalytic power of titanium dioxide (TiO2) to purify
the air and eliminate bacteria is a well-known phenomenon, but
not everyone knows that the benefits depend largely on the
micrometric rather than nanometric dimensions of TiO2, in a
process that involves no risks to human health or the
environment during manufacture, application or final use. The
most interesting case is Graniti Fiandre’s ACTIVE Clean Air &
Antibacterial Ceramic™ tiles. The photocatalyst is not consumed
in the oxidation process, which uses only substances present in
the air to break down pollutants into a form which is not
damaging to the health, but activates and accelerates the
reaction. Its particles are not directly involved, with the
result that the action of the titanium dioxide remains unaltered
over the years. Fixing TiO2 on ACTIVE Clean Air & Antibacterial
Ceramic™ tiles at high temperatures ensures that the surface of
the tiles is extremely resistant to abrasion due to tread, even
in the presence of intense traffic, guara
