| 英文摘要 | co and formaldehyde (hcho) oxidation reactions were investigated over mesoporous ag/co3o4 catalysts prepared by one-pot (op) and impregnation (im) methods. it was found that the one-pot method was superior to the impregnation method for synthesizing ag/co3o4 catalysts with high activity for both reactions. it was also found that the catalytic behavior of mesoporous co3o4 and ag/co3o4 catalysts for the both reactions was different. and the addition of silver on mesoporous co3o4 did not always enhance the catalytic activity of final catalyst for co oxidation at room temperature (20 degrees c), but could significantly improve the catalytic activity of final catalyst for hcho oxidation at low temperature (90 degrees c). the high surface area, uniform pore structure and the pretty good dispersion degree of the silver particle should be responsible for the excellent low-temperature co oxidation activity. however, for hcho oxidation, the addition of silver played an important role in the activity enhancement. and the silver particle size and the reducibility of co3o4 should be indispensable for the high activity of hcho oxidation at low temperature. |
