TL;DR: This critical review of the nature of the active sites in copper containing zeolites for the selective conversion of methane to methanol considers the varied experimental evidence arising from the application of X-ray diffraction, and vibrational, electronic, andX-ray spectroscopies that exist, along with the results of theory.

TL;DR: Some oft-cited assumptions in this topic are scrutinized—which include the labelling of the process as biomimetic, the debate regarding the industrial viability of direct methane-oxidation systems and the claim that methane is difficult to activate—and the extent to which these are scientifically robust is delineated.

TL;DR: The potential of combined operando UV-Vis/Raman/XAFS has been explored by studying the active site and deactivation mechanism of silica- and alumina-supported molybdenum oxide catalysts under propane dehydrogenation conditions.

TL;DR: In this paper, time-resolved in situ, energy-dispersive X-ray absorption spectroscopy and mass spectrometry were used to correlate changes in the chemical state of alumina and ceria-supported palladium nanopartic materials.

TL;DR: The authors study the carbon dioxide hydrogenation mechanism using high-pressure operando techniques which allow them to unify different, seemingly contradicting, models and indicate that the copper–zinc alloy undergoes oxidation under reaction conditions into zinc formate, zinc oxide and metallic copper.
