چکیده انگلیسی
A series of Pd/Fe-containing catalysts were successfully prepared by a polyol reduction method and applied for low temperature CO oxidation. The effect of supports, Ce introduction and pH values on low temperature CO oxidation was investigated in detailed. The results showed that Fe(OH)x was a suitable support better than FeOx. Addition of suitable Ce was beneficial to increase the catalytic activity. HR-TEM showed that Pd species which prepared by a polyol reduction method were highly dispersed. Through the research, the Pd-Ce/Fe(OH)x catalyst could completely oxidize CO at room temperature and keep excellent stability for 500 h at 40 °C when reaction pH value was 10.5.
