The direct conversion of methane to methanol by the copper-exchanged zeolites
In this project, we would like to use the neutron powder diffraction (NPD) technique for studying the process of the partial oxidation of methane to methanol (MtM) by active copper species in various Cu-zeolite structures. The objective is to determine whether the methoxy forms on copper monomers, dimers or higher nuclearity clusters, which is currently heavily debated in the scientific community. The positioning of hydrocarbon species will also show the distribution of copper species and elucidate if the activity increases only because of increased density of active species or structural differences in the zeolite framework. In situ neutron powder diffraction measurement should provide excellent contrasts for methane and methoxy species if labelled with deuterium (b= 6.67 fm).
