The CuO-CeO_2/Al_2O_3/FeCrAl monolithic catalysts were prepared by impregnation, dip-coating, deposition-impregnation, sol-pyrolysis, in situ combustion, and microemulsion methods. The influence of the preparation methods on active component distribution, catalyst structure, adherence, and catalytic properties was investigated by scanning electron microscopy, X-ray diffraction, temperature-programmed reduction, and ultrasonic and thermal vibration tests. The monolithic catalyst samples prepared by sol-pyrolysis, in situ combustion, and microemulsion presented good catalytic performance for CO preferential oxidation and high adherence stability.
