Metal-free heteroatom doping of carbon nitride for enhanced photocatalytic hydrogen peroxide production
Eneko Sebastian-Garate, Bruna F. Gonçalves, Jordi Llusar +5
The photocatalytic production of hydrogen peroxide (HO) from water is a promising strategy for solar-to-chemical energy conversion. Herein, we investigate the effect of met…
Charge Transfer from Perovskite Quantum Dots to Multifunctional Ligands with Tethered Molecular Species
Mariam Kurashvili, Lena S. Stickel, Jordi Llusar +6
Perovskite quantum dots (pQDs) are promising materials for optoelectronic and photocatalytic applications due to their unique optical properties. To enhance charge carrier extracti…
Fuzzy band structure of quantum dots by Bloch Orbital Expansion, unconventional insights into geometry-electronic structure relations
Zeger Hens, Jordi Llusar, Ivan Infante
The extension of ab-initio methods like density functional theory (DFT) to quantum dot (QD) geometries has enabled researchers to explore relationships between QD surface terminati…
Interfacial Reconstructions and Engineering in III-V@II-VI Core-Shell Quantum Dots
Jordi Llusar, Abdessamad El Adel, Luca De Trizio +3
In core/shell quantum dots (QDs), the interface between semiconductors of different chemical character largely determines their optoelectronic properties. In III-V/II-VI systems, t…
Exogenous Metal Cations in the Synthesis of CsPbBr3 Nanocrystals and their Interplay with Tertiary Amines
Zhanzhao Li, Luca Goldoni, Ye Wu +9
Current syntheses of CsPbBr3 halide perovskite nanocrystals (NCs) rely on over-stoichiometric amounts of Pb2+ precursors, resulting in unreacted lead ions at the end of the process…
Improving the Stability of Colloidal CsPbBr3 Nanocrystals with an Alkylphosphonium Bromide as Surface Ligand Pair
Meenakshi Pegu, Hossein Roshan, Clara Otero-Martinez +9
In this study, we synthesised a phosphonium-based ligand, trimethyl(tetradecyl)phosphonium bromide (TTP-Br), and employed it in the post-synthesis surface treatment of Cs-oleate-ca…
