| 英文摘要 | catio3-and batio3-supported ag and pt catalysts were subjected to cyclic oxidation and reduction treatments and their surface structures were investigated using x-ray diffraction (xrd) and x-ray photoelectron spectroscopy (xps). the co oxidation reactions over the ag and pt catalysts showed that the oxidized ag/oxide catalysts performed better in co oxidation than the reduced ones did, whereas the reduced pt/oxide catalysts had higher co oxidation activity than that after oxidation treatment. the xrd and xps measurements revealed that the oxidation treatment helped to improve the dispersion of ag nanoparticles, but their metallic state was retained, which enhanced co oxidation. in contrast, the surfaces of the pt nanoparticles were dominated by pto2 after the oxidation treatment, which lowered the co oxidation activity compared with that of the reduced pt catalyst.
