抄録

Three Pt-CuO nanocatalysts PtCu/Al, PtCu/CeAl and PtCu/Ce have been successfully prepared. The characterization of the catalysts was examined by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), X-ray energy dispersive analysis (EDS), temperature-programmed reduction (TPR), nitrogen physisorption measurements, and IR-CO adsorption. The kinetics of CO oxidation using these catalysts was studied in a gradientless flow-circulating system at 398–498 K. The obtained kinetic equation confirmed that the reaction proceeds in medium surface coverage with the participation of CO molecules and oxygen atoms.
