Proposed project is focused on increasing activity of the photocatalysts utilized in the water treatment technology. A series of photocatalysts exposed with specific crystal facets will be prepared and systematically modified, in order to achieve possibly high photocatalytic activity. It is expected that combination of a specific crystal facet exposed, introduced dopants and surface co-catalysts should remarkable increase photocatalyst quantum efficiency. Furthermore, obtained materials will be tested towards their ability to generate different reactive oxygen species which should initiate degradation process. Finally, characterized materials will be tested in the removal of selected different pollutants from aqueous phase (pharmaceuticals, pesticides, heavy metals and PAHs). Obtained results should provide key information about design of the highly active, multi-component photocatalytic systems, as well as they will act as a base for further studies and/or applications made by the PG's photocatalysis team.

The interplay between dopant and a surface structure of the photocatalyst – The case study of Nb-doped faceted TiO2
PublicationAnatase nanoparticles, exposing the majority of the {0 0 1}, {1 0 0} and {1 0 1} facets were synthesized and doped with different niobium amount to investigate the self-trapping of the excess electrons and resulting photocatalytic activity. Photocatalyst structure and presence of excess electrons inside the obtained Nb-doped anatase samples was confirmed by the combination of structural and spectroscopic analyses. Only for the...
