Synthesis and characterization of an immobilizable photochemical molecular device for H-2-generation

With Ru-II(bpyMeP)(2)tpphzPtCl(2) (4) a molecular photocatalyst has been synthesized for visible-light-driven H-2-evolution. It contains the ligand bpyMeP (4,4'-bis(diethyl-(methylene)-phosphonate)-2,2'-bipyridine) with phosphate ester groups as prec ...

An Integrated Device View on Photoelectrochemical Solar-Hydrogen Generation

Sophia Haussener, Miguel Antonio Modestino

Devices that directly capture and store solar energy have the potential to significantly increase the share of energy from intermittent renewable sources. Photo-electrochemical solar-hydrogen generators could become an important contributor, as these devic ...

Electron-Phonon Coupling in the Bulk of Anatase TiO2 Measured by Resonant Inelastic X-Ray Spectroscopy

Marco Grioni, Arnaud Magrez, Helmuth Berger, Philippe Bugnon, Simon Karl Moser, Sara Fatale

We investigate the polaronic ground state of anatase TiO2 by bulk-sensitive resonant inelastic x-ray spectroscopy (RIXS) at the Ti L-3 edge. We find that the formation of the polaron cloud involves a single 95 meV phonon along the c axis, in addition to th ...

Double D-pi-A Dye Linked by 2,2'-Bipyridine Dicarboxylic Acid: Influence of para- and meta-Substituted Carboxyl Anchoring Group

Michael Graetzel, Mohammad Khaja Nazeeruddin, Peng Gao, Aravind Kumar Chandiran, Paramaguru Ganesan

Starting from 2,2-bipyridine dicarboxylic acid, two new (D--A)(2) sensitizers, including m-DA with the carboxyl anchoring group substituted meta to the donor-bridge moiety and p-DA with a para-substituted anchoring group, were synthesized in order to evalu ...

Low-temperature, solution-deposited metal chalcogenide films as highly efficient counter electrodes for sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Bing Zhang, Feng Liu, Linhua Hu

Transition metal chalcogenide crystalline films FeSe2, Cu1.8S, and CuSe have been deposited from solution by drop casting their dissolved inks onto a conductive substrate, followed by a mild thermal treatment. We demonstrate that the resulting chalcogenide ...

Manipulating nanocrystal doping, structure, and photocatalytic activity with organic ligands

Raffaella Buonsanti, Anna Loiudice

Org. ligands (or surfactants) are key in detg. colloidal nanocrystal structure and, therefore, function. In addn. to their more traditional role as surface passivating agents impacting nanocrystal size and shape, surfactants can also behave as active reage ...

TiO2 Anatase with a Bandgap in the Visible Region

Klaus Kern, Christian Alexander Stephan Dette, Feliciano Giustino, Christopher Seiji Kley

TiO2 anatase plays a central role in energy and environmental research. A major bottleneck toward developing artificial photosynthesis with TiO2 is that it only absorbs ultraviolet light, owing to its large bandgap of 3.2 eV. If one could reduce the bandga ...

Proximal gap-plasmon nanoresonators in the limit of vanishing inter-cavity separation

Giulia Tagliabue, Dimos Poulikakos

Nanostructured metal–insulator–metal (MIM) metasurfaces supporting gap-plasmons (GPs) show great promise due to their ability to manipulate or concentrate light at the nanoscale, which is of importance to a broad palette of technologies. The interaction be ...
