Mesoporous TiO2-rutile supported MnxOy-Na2WO4: Preparation, characterization and catalytic performance in the oxidative coupling of methane

Abstract

The oxidative coupling of methane (OCM) is one of the most important direct method to convert natural gas into value added products. For the first time in literature mesoporous TiO2-rutile supported MnxOy-Na2WO4 catalyst was prepared, characterized and tested in the OCM. The activity parameters (X-CH4, S-C-2, Y-C-2) did not change substantially during the reaction and they were mostly stable. The MnxOy-Na2WO4/mes-TiO2-rutile catalyst seems to have promising potential for the OCM. Moreover, when it is compared with commercial TiO2-rutile and TiO2-anatase supported catalysts in literature, it can be concluded that it is a candidate showing even better performance in the OCM.
