Randomized trial demonstrates efficient methane conversion to acetic acid using dual-site catalysts, suggesting advances in natural gas utilization.

This research aims to improve the efficiency of methane conversion to acetic acid using dual-site catalysts.
Developed dual-site catalysts based on Fe–Rh interactions confined in ZSM-5.
Conducted oxidative carbonylation of methane under mild conditions with in situ H2O2 generation.
Utilized in situ spectroscopy to study reaction pathways.
Achieved a CH3COOH yield of 10.24 mmol/g cat./h with 75.2% selectivity at 140 °C.
Demonstrated that adjacent Rh-Fe coupling enhances efficiency by generating hydroxyl radicals.
The dual-site design model is applicable to other complex reactions like methane combustion and selective oxidation.
