Improved charge carrier separation in barium tantalate composites investigated by laser flash photolysis

Schneider, Jenny; Nikitin, Konstantin; Wark, Michael; Bahnemann, Detlef W.; Marschall, Roland (Cambridge : Royal Society of Chemistry, 2015-12-15)

Charge carrier dynamics in phase pure Ba5Ta4O15 and in a Ba5Ta4O15–Ba3Ta5O15 composite have been studied by means of diffuse reflectance laser flash photolysis spectroscopy in the presence and absence of an electron donor, ...
Interparticle Interaction Matters: Charge Carrier Dynamics in Hybrid Semiconductor–Metal Cryoaerogels

Schlosser, Anja; Schlenkrich, Jakob; Zámbó, Dániel; Rosebrock, Marina; Graf, Rebecca T.; Escobar Cano, Giamper; Bigall, Nadja C. (Weinheim : Wiley-VCH, 2022-02-18)

Integration of noble metals into semiconductor-based nanoparticle gel structures facilitates the extraction of photoexcited charge carriers upon illumination. While charge carrier generation takes place in the semiconductor ...
Investigation of the Photocatalytic Hydrogen Production of Semiconductor Nanocrystal-Based Hydrogels

Schlenkrich, Jakob; Lübkemann‐Warwas, Franziska; Graf, Rebecca T.; Wesemann, Christoph; Schoske, Larissa; Rosebrock, Marina; Hindricks, Karen D. J.; Behrens, Peter; Bahnemann, Detlef W.; Dorfs, Dirk; Bigall, Nadja C. (Weinheim : Wiley-VCH, 2023)

Destabilization of a ligand-stabilized semiconductor nanocrystal solution with an oxidizing agent can lead to a macroscopic highly porous self-supporting nanocrystal network entitled hydrogel, with good accessibility to ...
One‐Step Formation of Hybrid Nanocrystal Gels : Deposition of Metal Domains on CdSe/CdS Nanorod and Nanoplatelet Networks

Zámbó, Dániel; Schlosser, Anja; Graf, Rebecca T.; Rusch, Pascal; Kißling, Patrick A.; Feldhoff, A.; Bigall, Nadja C. (Weinheim : Wiley-VCH, 2021-05-29)

Hybrid semiconductor-based nanocrystals (NCs) are generally synthesized in organic media prior to their assembly into catalytically promising nanostructures via multistep methods. Here, a tunable, easy-to-adapt and versatile ...
