| Abstract Scope |
TiO<SUB>2</SUB> is an important photoactive material with existing and potential uses in a wide variety of environmental and energy applications, such as photocatalytic oxidation of dyes and contaminants and dye-sensitized photovoltaic cells. Also as biomaterial, TiO<SUB>2</SUB> has already proved to have a positive influence on human cell growth and cell differentiation. The performance of TiO<SUB>2</SUB> is influenced by the fraction of anatase, its crystallinity, particle size and the surface area. In this work, a low temperature hydrothermal method for the synthesis of a stable dispersion of anatase TiO<SUB>2</SUB> nanoparticles of 10 wt% in water is developed. This dispersion is used for the deposition of different nanostructures (dense, patterned and porous films) via wet chemical deposition techniques. The different layers’ performance is evaluated in specific setups representing the real environment of the envisioned applications.A.Hardy and C.De Dobbelaere are post-doctoral research fellows of the Research Foundation-Flanders (FWO Vlaanderen). |
