Abstract

Recently, we reported a novel, low temperature route for the selective and catalyticoxidation of methane to methanol, an immense scientific and practical challenge.1 Along with proceeding at unrivalled levels of methanol selectivity, the system in question operates at rates over three orders-of-magnitude larger than any previously observed for this challenging reaction, and in a full, closed catalytic cycle. The key to this process is the activation of the terminal oxidant, H2O2, with a Cu-promoted Fe-containing zeolite (Cu-Fe-ZSM-5), which provides a low energy pathway for the conversion of methane to methyl hydroperoxide, which subsequently converts in situ to methanol.2 During this presentation, the precise roles of the catalytic active sites (Fe and Cu) will be discussed, both in terms of methane activation and methanol over-oxidation. It will be shown that by understanding the molecular events influenced by the catalyst, its macroscopic performance can be enhanced by tailoring both the structure/morphology of the catalyst, and the reaction conditions.
