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, ...

There is an increasing number of research reports [5–13] on the TiO2
immobilization to develop photocatalytic fabrics used in applications as
wastewater treatment, indoor air purification, or as self-cleaning, self-
decontaminating or antibacterial fabrics. Different substrates are reported:
polyester [5, 6], wool [7, 8], cellulose [9] cottonpolyester blends [10] or cotton
fabrics [8, 11, 12]. The great interest in producing the photocatalytic fabrics arise
from their good activity, large availability, low ...

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 ...

This photocatalytic effect can be exploited for various commercial applications,
such as water and air purification, or to impart self-cleaning, antimicrobial, and
antialgae properties to surfaces. Since all such reactions take place very close to
the surface (of the TiO2 particles or coating), nanoparticles with extremely high
surface area allow these reactions to proceed at orders-of-magnitude faster rates
than ordinary grades of the oxide.2 Such photocatalytic reactions can be used to
treat, ...
