Method for preventing air pollution: Methane oxidation by two types of catalysts

Methane oxidation using different catalysts is an useful process for preventing air pollution. This study presents the methane oxidation by two types of catalysts: Pd-Sn/Al₂O₃ and spinel mixed oxide, CuFe₂O₄. The Pd-Sn/Al₂O₃ was successfully prepared by sol-gel method and CuFe₂O₄ by co-precipitation method. The catalysts obtained have been characterized structurally, morphologically and texturally by X-ray diffraction (XRD), scanning electron microscopy (SEM) and specific surface area (BET). The catalytic activity tests regarding methane oxidation were also performed.
