| Abstract: The structure and catalytic properties of SrTiO3 perovskite-type oxide catalysts for oxidative coupling of methane (OCM) have been studied by using X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and microreactor tests. It has been shown that OCM catalytic properties of SrTiO3 catalysts are correlated to the Sr/Ti atomic ratio. Increasing Sr/Ti ratio in the perovskite-type SrTiO3 catalysts results in the surface enrichment of Sr element, leading to the the higher content of adsorbed oxygen species on the surface of catalysts and thus higher C2 selectivity for OCM reaction. |
