In self-cleaning glasses, thin TiO2 coatings exhibit photocatalytic and hydrophilic
properties as shown in figures 9 and 10 [3][7]. Another advantage of this process
is reduction in the lighting cost due to the fact that daylight is less obscured by
surface dirt. In addition to selfcleaning, the surfaces also exhibit antimicrobial,
antifogging and air-purification properties. So any advances in this field not only
saves energy and labour costs, but could also aid reduce hazardous substances
and ...

The photocatalytic and antimicrobial properties are used in “self-cleaning
products (e.g., windows, cement, tiles, and textiles for use in hospitals) and air
purification systems. Use of tribological coatings prevents deposits in engines
and enhances fuel efficiency. TiO2 nanoparticles are also used to increase
scratch resistance of coatings and in the production of electronic components
and dental impressions. TiO2 can also be used in dye-sensitized solar cells to
produce electricity, ...

In addition to the self-cleaning properties, photocatalysis can also be used to
achieve air-purifying, water- purifying as well as antimicrobial properties. An
interesting application, which has already been implemented in experimental
prototype form, is the exploitation of the cooling effect of evaporating water. The
canvas and steel roofing as well as the windows of a trade fair pavilion in Japan (
Expo 2005, Aichi, Nagakute area) were equipped with a photocatalytic Ti02
coating and ...

the nanometer-sized polymers prepared by microwave-assisted symmetry break-
up of polymer thin films display exceptional antimicrobial properties compared to
TiO2 film. The nanotextured surface also exhibit hydrophobic and self-cleaning
properties (Fig. 2b). A company sponsored research had successfully developed
a new process for preparing nanotextured TiO2 on large area surfaces for
application in sanitary coatings. Entrapping photoactive TiO2 within the silica
network of ...

Titanium dioxide has been extensively studied for environmental remediation
applications, such as the purification of air!”] and water," antibacterial activity,"
and self-cleaning coatings." These applications rely on the photoactive properties
of TiO2. Much research has been conducted in an attempt to improve the
photocatalytic activity of titania by changing the bulk electronic properties or
modifying the surface properties of the material.” For example, both the
