Photo(electro)chemical and surface characterization of semiconductor photocatalysts/materials

Semiconductor photocatalysts as TiO2 or hematite can find use in environmental or energy applications. TiO2 based materials are able (after irradiation with UV light) to generate on the surface highly reactive radicals capable to remove pollutants from air (NOx, toluene, acetaldehyde), water (dyes, herbicides) or to create a self-cleaning surface able to decompose solid organic deposits. Among other semiconductor materials, hematite (α-Fe2O3) can be successfully used as a photoanode for light-assisted water electrolysis. It is due to its favourable band gap (2.1 eV) resulting in the theoretical maximum power conversion efficiency of 27 %. Our research is mainly focused on the development of various photocatalyst materials and optimisation of their functional properties through their physical and photoelectrochemical characterization.
