Methane oxidation was carried out in presence of synthetized Pt/Al2O3–CeO2 catalysts with ceria contents between 1 and 37 mol%, at 823 K, 52,000 h−1 of GHSV, by varying the oxygen concentration from a deficient concentration respect to methane (1 mol:1 mol) up until a 100% excess over the stoichiometric (4 mol:1 mol). The catalysts were characterized by TGA, N2 sorption, XRD, TPR, UV–Vis, TPD-NH3, and ICP for elemental composition, while methane conversion was followed by gas chromatography. It… Expand


Pt catalysts supported on mixed CeO2-Al2O3 carriers with different CeO2 loadings (2–50 wt.%) were prepared by the sol-gel method. Several techniques such as N2 physisorption, X-ray diffraction (XRD),Expand
Low-temperature oxidation of carbon monoxide and methane over alumina and ceria supported platinum catalysts
