Titania (TiO2) is suitable for several environmental applications such as air purifier, waste water treatment cleaning, water disinfection and photo-induced hydrophilic coating with self-cleaning properties. It can be incorporated in bulk concrete, mortars, ceramic or as a coating on glass and stone.

The selection of the appropriate matrix is of importance since it can affect the effectiveness of nanomaterials, or even react in such a way that unwanted by-products may be produced.   The presence of dissolved oxygen in the liquid phase is expected to enhance photocatalytic oxidation since oxygen traps the photogenerated electrons to form superoxide radical anions. Nonetheless, attention should be paid to the possibility of water penetration inside the building matrices with the use of nanomaterials.

There are many examples of photocatalysts aimed at reducing urban depollution applied on photocatalytic pavements. Titanium dioxide (Titania) is being explored as a component, but the correct method of applying photocatalysts in pavements is still being investigated. Mixed with the binder, the TiO2 was not effective in degrading NOx in the air. As a surface spray coating however, Titania was very effective in removing nitrogen oxide.

The size of the nanoparticles is an important factor, when it comes to the photocatalytic performance. Nanomaterials with smaller particles are expected to provide better photocatalytic activity.

Self-cleaning/photocatalytic properties are known since the 1960s, but they have only recently been widely exploited. The first application was on the church ‘‘Dives in Misericordia” in Rome. It is composed of 346 self-cleaning concrete blocks made of white cement and TiO2. Another example was a pilot project in Antwerp, Belgium, consisting of 10.000 m2 of photocatalytic pavement blocks, constructed in 2004–2005 on the parking lanes of a main road.

Photocatalysis is the activity occurring when a light source interacts with the surface of semiconductor materials, the so called photocatalysts. During this process, there must be at least two simultaneous reactions occurring, oxidation from photogenerated holes, and reduction from photogenerated electrons. The photocatalyst itself should not undergo change and therefore a precise synchronisation of the two processes needs to take place.

by Dimitra Papadaki (NKUA)   The growing field of nanotechnology can be found in healthcare, electronics, cosmetics, information technology, and environmental protection, but also in the building sector. It involves the production of materials and structures (nanomaterials) at a scale of 100 nanometres or less.

An increasing number of people are becoming environmentally conscious, resulting in a record breaking growth of the solar energy production. The global solar output has more than trebled in last four years. Solar power generation enjoyed another year of exceptionally rapid growth in 2016, with a 29.6% increase. The highest growth was recorded in China (34.5 GW) and the US (14.7 GW), together accounting for two-thirds of the growth in global solar capacity. However, increasing awareness is not the only factor responsible for this rapid growth.
