We found that two simultaneous effects occur in water: an electrochemical degradation and a photocatalytic degradation of the pollutants. Furthermore, the existence of a synergetic effect was observed which is explained by the electron-hole pair separation in the electric field which increases the lifetime, even when the electric field is small.<eng> vorgelegt von Adwaa Ahmed GutachterInnen: Eberhard Burkel (University of Rostock, Physics of New Materials) ; Igor Khmelinskii Khmelinskii (Faculty of Sciences and Technology, University of Algarve, Faro, Portugal) Dissertation Universität Rostock 2020 530 530.4175 530 http://purl.uni-rostock.de/rosdok/id00002963 https://doi.org/10.18453/rosdok_id00002963 https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00002963-9 https://d-nb.info/1293533939/34 Spectral characteristics of photocatalytic constant for titania--(DE-627)1750554119 urn:nbn:de:gbv:28-rosdok_id00002963-9 doi: 10.18453/rosdok_id00002963 oclc: 1240236299 ppn: (DE-627)1750135205
