| Abstract: | This work described in situ combustion synthesis method for depositing CuO-CeO2 on the FeCrAl honeycomb supports. The influence of the solution concentration and the role of the additive were studied and analyzed by scanning electron microscopy (SEM), X-ray diffractometer (XRD), and temperature programmed reduction (TPR) techniques. The results showed that 200 g/L of the active solution was the most appropriate concentration for preparing the monolithic catalysts, and the additives of praseodymium and lanthanum improved the adhesion stability of the monolithic catalysts. The addition of Pr did not greatly affect the catalytic performance, but CO could not be totally converted into CO2 after the addition of La into the CuO-CeO2/Al2O3/FeCrAl catalysts. |
