Beyond Canonical CO Oxidation: Structural and Evolutionary Insights Into a Non‐Canonical Carbon Monoxide Dehydrogenase

Angewandte Chemie, EarlyView.
Clade B carbon monoxide dehydrogenases (CODHs) remain enigmatic, diverging from canonical CODHs in structure and function. Here, we present the first characterization of Ruminococcus flavefaciens CODH (RfCODH), revealing occluded substrate pathways and attenuated CO oxidation activity.

Measuring Local Exothermic Effects During the Oxidative Coupling of Methane Using Operando Luminescence Thermometry

Angewandte Chemie, EarlyView.
Operando luminescence thermometry shows that the local catalyst temperature can exceed the set oven temperature by almost 250°C during the exothermic oxidative coupling of methane process. We demonstrate how the reactor dimensions, catalyst grain size, and reactant feed mixture affect the local temperature.
