Investigation of perovskite catalysts BaTiO3 and SrTiO3 for the oxidative coupling of methane

In this study, perovskite BaTiO3 and SrTiO3 catalysts were prepared using the sol-gel method for oxidative coupling of methane (OCM). Characterization of catalysts was investigated by X-ray diffraction for crystal properties, physical N2 adsorption to determine specific surface area, and temperatureprogrammed techniques to examine the redox properties and acid–base strength.
