| description | An improved methane oxidation catalyst including tin oxide-supported platinum exerts superior methane oxidation activity at lower temperatures. The methane oxidation catalyst for oxidizing methane in exhaust gas includes platinum supported on tin oxide, and satisfies formula (1): y ≤ 0.27 x, where x is a platinum content (wt%) relative to tin oxide, and y is a ratio of a peak intensity of (111)-faceted platinum relative to a peak intensity of (111)-faceted tin oxide (Pt(111)/SnO(111)), in a diffraction pattern (2θ = 37 to 41°) obtained by measurement with an X-ray diffractometer (XRD). |
