Site-selective X-ray spectroscopy on an asymmetric model complex of the [FeFe] hydrogenase active site.
The results suggest that metal site- and spin-selective XAES on [FeFe] hydrogenase protein and active site models may provide a powerful tool to study intermediates under reaction conditions. Expand
A biomimetic pathway for hydrogen evolution from a model of the iron hydrogenase active site.
A Biomimetic Pathway for Hydrogen Evolution from a Model of the Iron Hydrogenase Active Site and its consequences are illustrated. Expand
Model of the iron hydrogenase active site covalently linked to a ruthenium photosensitizer: synthesis and photophysical properties.
IR and electrochemical studies reveal that the nitrogen heteroatom of the ADT bridge has a marked influence on the electronic properties of the [Fe2(CO)6] core. Expand
High-turnover photochemical hydrogen production catalyzed by a model complex of the [FeFe]-hydrogenase active site.
Investigations of photo- and electrocatalytic hydrogen production with natural and synthetic molecular catalysts provide detailed kinetic and mechanistic information on the catalyst itself, and it is possible to distinguish between alternative catalytic pathways and to extract rate constants for individual steps of catalysis.

Introducing a dark reaction to photochemistry: photocatalytic hydrogen from [FeFe] hydrogenase active site model complexes.
Covalently linked dyads, supramolecular assemblies and multi-component systems will be examined with an emphasis on mechanistic electron transfer schemes, the properties of the individual components, their scope and their potential limitations. Expand
Catalytic hydrogen evolution from mononuclear iron(II) carbonyl complexes as minimal functional models of the [FeFe] hydrogenase active site.
How much iron does it take? Mononuclear complexes [FeII(3,6-R2bdt)(CO)2(PMe3)2] (bdt=1,2-C6H4(S−)2; R=H, Cl) can be reversibly protonated at the sulfur ligands, can catalyze the electrochemical redExpand
A model of the [FeFe] hydrogenase active site with a biologically relevant azadithiolate bridge: a spectroscopic and theoretical investigation.
Convincing evidence for the presence of a nitrogen atom in the dithiolate bridge of the active site of native [FeFe] hydrogenases (B) is provided by a spectroscopic, electrochemical, and theoreticaExpand
Electronic structure of an [FeFe] hydrogenase model complex in solution revealed by X-ray absorption spectroscopy using narrow-band emission detection.
Two routes of facilitated bridging hydride binding thereby are suggested, involving ligand rotation at Fe1 for 1Hy(CO) or adt-N protonation for 1HHy(CO,Ph). Expand
Water oxidation catalysed by a mononuclear Co(II) polypyridine complex; possible reaction intermediates and the role of the chloride ligand.
Experimental evidence points towards the presence of a chloride ligand at the cobalt centre throughout the catalytic cycle, and the temporary detachment of a pyridine ligand to open a coordination site for substrate binding. Expand
Product Profiles: Modelling customer benefits as a foundation to bring inventions to innovations
More than 100 product profiles and their development in three Live-Labs with industrial participation as well as three industrial innovation projects are analyzed and a definition of product profiles is derived and a product profile scheme to model profiles is introduced. Expand
