Abstract:
Heterogeneous aerobic oxidation using molecular oxygen (O2) represents a versatile and sustainable platform for the synthesis of oxygenates and nitrogen-containing chemicals. This review systematically summarizes recent advances in fundamental principles of molecular oxygen activation, catalyst design, reaction mechanisms for key oxidative transformations, including the oxidative dehydrogenation of alkanes, the epoxidation of alkenes, ammoxidation, ammoximation, oxidative cleavage or nitridation, and the oxidative upcycling of waste plastics. The fundamental challenge of activating triplet O2 is addressed through strategies such as altering electron transfer, chemisorption-dissociation, lattice oxygen participation (Mars-van Krevelen mechanism), and the formation of active oxygen complexes. By comparing catalytic systems, such as MoVNbTeOx for ethane ODH, Ag/α-Al2O3 for ethylene epoxidation, Au/TS-1 for propylene epoxidation, and emerging oxidative upcycling of plastics, we extract general principles for enhancing catalytic activity, selectivity, and stability. Future perspectives highlight the role of advanced characterization, atomic-scale catalyst engineering, and process intensification in enabling the industrial implementation of aerobic oxidation technologies, ultimately contributing to a greener and circular chemical economy.

Fates of Pyruvate
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...
