AI Article Synopsis
- The study investigates how O2-activated Cu-ZSM-5 and Cu-MOR zeolites convert methane into methanol at 398 K.
- The research highlights a significant link between the activity of the zeolites and the strength of a specific UV-vis band related to the bis(mu-oxo)dicopper core.
- Findings suggest that this bis(mu-oxo)dicopper core is crucial for enabling selective conversion of methane to methanol at low temperatures.
Article Abstract
This work reports on the capability of the O2-activated Cu-ZSM-5 and Cu-MOR zeolites to selectively convert methane into methanol at a temperature of 398 K. A strong correlation between (i) the activity and (ii) the intensity of the 22 700 cm-1 UV-vis band, assigned to the bis(mu-oxo)dicopper core, is found (i) as a function of the reaction temperature, (ii) as a function of the Cu loading of the zeolite, and (iii) in comparison to other Cu materials. These three lines of evidence firmly support the key role of the bis(mu-oxo)dicopper core in this selective, low-temperature hydroxylation of methane.
