Concerted Proton and Electron Transfer in Heterogeneous Electrocatalytic CO2 Reduction

Angewandte Chemie, EarlyView.
Concerted proton‐electron transfer (CPET) enables CO2‐to‐CO conversion with significantly reduced energy cost compared to cation‐stabilized pathways. Under controlled mass transport of proton donors, CPET dominates at modest potentials. At higher overpotentials, a cation‐stabilized pathway is found to dominate.

A Homogeneously Catalyzed Paired Electrolytic Cell for Hydrogen Peroxide Production

Angewandte Chemie, EarlyView.
Cu(tmpa) and Sn‐TMPyP are compatible and efficient catalysts for 2e−‐ORR and 2e−‐WOR, respectively, which have been employed to assemble an efficient paired electrochemical cell for H2O2 production. The presence of a carbonate buffer is essential to achieve a high activity in the anode compartment, while control over mass transport is essential for a ...

Monitoring Redox Pathways and Performance Limitations in Lithium‐Sulfur Batteries Using In Situ 7/6Li and 33S NMR Spectroscopies

Angewandte Chemie, EarlyView.
Lithium‐sulfur (Li‐S) batteries contain various NMR‐active nuclear isotopes, including 7Li, 6Li and 33S, which are sensitive to the different chemical reactions that occur during battery cycling. Herein, we use a combination of lithium and sulfur operando NMR spectroscopy to provide new insights at the molecular level, fundamental understanding being ...

Chemical Metabolomics: Chemical Biology Tools for Advanced Metabolism Investigations

Angewandte Chemie, EarlyView.
The human metabolism has been investigated for several millennia. The metabolome is known for a high complexity due to a large number of different metabolites that are present at different concentrations. Metabolomics has been developed as a field to investigate the entire human metabolome and to elucidate disease development mechanisms.

Two‐Dimensional Infrared Spectroscopy Reveals the Presence of a Bridging CO Ligand in Two Catalytic Intermediates of [FeFe] Hydrogenase

Angewandte Chemie, EarlyView.
Two‐dimensional (2D) infrared (IR) spectroscopy provides vastly more structural and functional insight into chemical and biological systems than linear IR spectroscopy. Here, we apply 2D‐IR spectroscopy to two controversially discussed states of the [FeFe] hydrogenase active site, revealing the presence of a bridging carbonyl ligand, which is difficult
