Recent abundance of natural gas rejuvenated interest in catalytic methods leading to its high value products. We will focus on the molecular structure and properties of Oxidative Coupling of Methane (OCM) catalyst. Emphasis will be on using spectroscopy tools to interrogate the active site of OCM supported Na promoted tungstate catalyst with the goal of later controllably synthesizing it. In particular, controlled structure catalysts synthesized using incipient wetness impregnation below monolayer coverage were interrogated using in situ Raman measurements combined with mass spectroscopy. Molecular structure calculations of monomer WOx on SiO2 and Al2O3 will be presented to complement and explain spectroscopy measurements.
