Valorisation of Greenhouse Gas for Commodity Chemical Production–Nitrous Oxide as Oxidising Agent for Heterogeneous Catalysis

open access: yesChemSusChem, EarlyView.
Heterogeneous catalysts can enhance the selectivity of oxidation reactions using N2O as oxidizing Agent with proper modification of catalyst phase, surface area, and acidity. N₂O activation leads to generating reactive oxygen species, facilitating selective oxidation and dehydrogenation to produce various products such as oxygenates, hydrocarbons, and ...
