In this context main attention

In this context main attention is focused on heterogeneous photocatalysis using oxide semiconductors (Chatzisymeon et?al., 2013 and Robertson, 1996). Heterogeneous photocatalysis, also called the “green” technology, represents one of the main challenges in the field of treatment and decontamination of water and air because it SKLB610 is able to work at ambient temperature and atmospheric pressure. Its operating principle is based on the simultaneous action of the light source (such as solar light) and a catalyst (semi-conductor), which allows the degradation of organic pollutants without damaging the surrounding environment (Bernardini et al., 2010). For many years titania (TiO2) based photocatalysts have received intense attention as promising photocatalytic materials (Hoffmann et al., 1995).
However, photocatalysts suffer for the layout of photocatalytic plants, where the most limitation regards the low activity of commercial TiO2 samples and the effective transferring of the light towards the overall amount of photocatalyst. The key parameter for a successful implementation of photocatalytic processes at large scale is the reduction of reaction time.
