Obiettivo del progetto (Objective)
'Although environmental remediation by TiO2 photocatalysis has become increasingly interest among scientists in recent years, wide range application is still limited by its absorption below 400 nm. UV photons are much more expensive compared to visible ones, as the latter compose a large fraction of solar energy (UV light compose only 3% of the solar energy), and relatively cheap artificial light sources can be applied. In order to achieve a break through in photocatalytic applications of TiO2 and other stable semiconductor materials (mostly oxides), the photocatalytic properties must be improved, either by red shifting of the light absorption and/or enhancing quantum yield by inhibition of recombination of photogenerated charge carriers (e-/h). TiO2 remains the most popular oxide semiconductor in photocatalysis R&D because of combination of unique features such as stability, low cost and high efficiency. It is believed that in addition to exploration of other oxides (e.g. WO3) and their mixtures, doping and surface modification of TiO2 is highly promising for increasing the efficiency and reducing the cost of photooxidation. Noble metals seem to be excellent modifiers, because they accelerate the transfer of photoexcited electrons of titania to substrates, and due to their photoabsorption inducing photocatalytic reaction under visible-light irradiation either by metal complexes fixed on titania or by photoexcitation of localized surface plasmon resonance (LSPR) of nanoparticles of noble metal. The present proposal concerns preparation and testing of new nanoparticle photocatalysts composed of metal oxides, as well as binary and ternary metal oxides/metal (metal complex) systems. The principle is the reduction of appropriate metal ions and ion mixtures with controlled structure and tunable nanoparticle size and composition. These new materials will be tested for catalytic and photocatalytic activity, as well as for water splitting and solar cells application.'
