| Abstract: | At room temperature,the catalytic oxidation of CO on Pd(Ⅱ)_Cu(Ⅱ)/activated carbon in the presence of air was studied.It was found that the catalytic activity of CO oxidation is dramatically enhanced when the air is saturated with water vapor.Based on the results obtained,the overall reaction order and apparent activation energy calculated are～1.3 and 50.46kJ·mol -1 respectively.The mechanism of CO oxidation on Pd(Ⅱ)_Cu(Ⅱ)/activated carbon was discussed at the same time. |
