Popis:	The catalytic combustion of propionic acid was chosen as a model reaction to investigate Pt structured catalysts. A novel competitive impregnation method was used to improve the condition of Pt distribution and decrease the Pt amount. The prepared catalysts were compared with those prepared by the co-impregnation method. Results showed that the competitive impregnation method was preferable. Cat com -0.06 with 0.06 wt.% Pt and 35.1% Pt dispersion was prepared by the competitive impregnation method, and this catalyst exhibited high activity and stability. The mechanism of the competitive impregnation method was also proposed.
