Design and synthesis of TiO2/C nanosheets with a directional cascade carrier transfer

Wu, Si-Ming; Wang, Yi-Tian; Xiao, Shi-Tian; Zhang, Yan-Xiang; Tian, Ge; Chen, Jiang-Bo; Zhao, Xiao-Fang; Janiak, Christoph; Shalom, Menny; Bahnemann, Detlef W.; Wang, Li-Ying; Yang, Xiao-Yu (Cambridge : RSC, 2022)

Directed transfer of carriers, akin to excited charges in photosynthesis, in semiconductors by structural design is challenging. Here, TiO2 nanosheets with interlayered sp2 carbon and titanium vacancies are obtained by ...
Effect of Cu2O Substrate on Photoinduced Hydrophilicity of TiO2 and ZnO Nanocoatings

Maevskaya, Maria V.; Rudakova, Aida V.; Emeline, Alexei V.; Bahnemann, Detlef W. (Basel : MDPI, 2021)

The effect of a Cu2 O substrate on the photoinduced alteration of the hydrophilicity of TiO2 and ZnO surfaces was studied. It was demonstrated that the formation of heterostructures Cu2 O/TiO2 and Cu2 O/ZnO strongly changed ...
Effect of the Type of Heterostructures on Photostimulated Alteration of the Surface Hydrophilicity: TiO2/BiVO4 vs. ZnO/BiVO4 Planar Heterostructured Coatings

Maevskaya, Maria V.; Rudakova, Aida V.; Koroleva, Alexandra V.; Sakhatskii, Aleksandr S.; Emeline, Alexei V.; Bahnemann, Detlef W. (Basel : MDPI, 2021)

Here, we report the results of comparative studies of the photostimulated hydrophilic behavior of heterostructured TiO2 /BiVO4 and ZnO/BiVO4, and monocomponent TiO2 and ZnO nanocoating surfaces. The chemical composition ...
Evaluating carbon dots as electron mediators in photochemical and photocatalytic processes of NiFe2O4

Ombaka, Lucy M.; Dillert, Ralf; Robben, Lars; Bahnemann, Detlef W. (College Park : American Institute of Physics, 2020)

Spinel ferrites such as nickel ferrite are promising energy conversion photocatalysts as they are visible-light absorbers, chemically stable, earth abundant, and inexpensive. Nickel ferrite shows poor photocatalytic activity ...
High kinetic energy-ion mobility spectrometry-mass spectrometry investigations of several volatiles and their fully deuterated analogues

Weiss, Florentin; Eiceman, Gary; Märk, Tilmann D.; Mayhew, Chris A.; Ruzsanyi, Veronika; Schaefer, Christoph; Zimmermann, Stefan (Berlin ; Heidelberg : Springer, 2022)

The first High Kinetic Energy-Ion Mobility Spectrometry-Mass Spectrometry (HiKE-IMS-MS) studies involving six volatiles (acetone, acetonitrile, methanol, ethanol, 2-propanol, and 1-butanol) and their fully deuterated ...
New insights into the surface plasmon resonance (SPR) driven photocatalytic H2 production of Au-TiO2

Nie, Jinlin; Schneider, Jenny; Sieland, Fabian; Zhou, Long; Xia, Shuwei; Bahnemann, Detlef W. (Cambridge : Royal Society of Chemistry, 2018)

The Surface Plasmon Resonance (SPR) driven photocatalytic H2 production upon visible light illumination (≥500 nm) was investigated on gold-loaded TiO2 (Au-TiO2). It has been clearly shown that the Au-SPR can directly lead ...
Noise enhancement due to quantum coherence in coupled quantum dots

Kießlich, G.; Schöll, E.; Brandes, T.; Hohls, Frank; Haug, Rolf J. (College Park, MD : American Physical Society, 2007)

We show that the intriguing observation of noise enhancement in the charge transport through two vertically coupled quantum dots can be explained by the interplay of quantum coherence and strong Coulomb blockade. We ...
Photo-excited charge transfer from adamantane to electronic bound states in water

Wang, Xiangfei; Krause, Pascal; Kirschbaum, Thorren; Palczynski, Karol; Dzubiella, Joachim; Bande, Annika (Cambridge : RSC Publ., 2024)

Aqueous nanodiamonds illuminated by UV light produce free solvated electrons, which may drive high-energy reduction reactions in water. However, the influence of water conformations on the excited-state electron-transfer ...
Understanding charge transfer processes on metal oxides - A laser-flash-photolysis study

Sieland, Fabian; Schneider, Jenny; Lippmann, Thorsten; Bahnemann, Detlef W. (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)

In the focus of this study, mixtures of commercially available TiO2 powders were created and their photocatalytic activity concerning the acetaldehyde degradation in the gas phase was tested. Further, the lifetime of the ...
