In‐Situ EPR Study of the Effect of SO2 Poisoning and Regeneration of Cu‐CHA Catalysts
In‐situ electron paramagnetic resonance highlights and quantifies the changes in the redox properties of copper chabazite catalysts for the SCR reaction after poisoning with SO2 and after regeneration at high temperature. Abstract A series of copper (Cu) exchanged chabazite zeolite with different Cu content were investigated to elucidate the effect of ...

In Situ Generation of Alkyl–λ3–Iodanes as Soft and Highly Reactive Electrophiles
A convenient and practical method for the clean generation of alkyl–λ3–iodanes is reported using tetraalkylsilanes and iodine tris(trifluoroacetate). An in situ‐generated methyl–λ3–iodane works as a soft and highly electrophilic methylation reagent, which enables methylation of tertiary sulfonamides at low temperatures and following transamidation and ...

Dysprosium in high‐symmetry environment: an original crystal‐field energetic profile provides an experimental demonstration of the oblate/prolate theory and is also responsible for an unprecedented orange‐to‐red emission. The importance of investigating high‐symmetry systems in order to reveal properties that would otherwise be concealed in less ...
