It is indicative of the TSR result that CH₄ was strongly adsorbed on well degassed SrCO₃ surface at high temperature. A desorption peak of CH₄ was found in CH₄-TPD profile which appeared at ca. 310℃. The strong adsorption of CH₄ over the surface of SrCO₃ was attributed to the strong basicity of SrO sites resulted from decomposition of SrCO₃.
