| 中文摘要 | mgo supported copper salt of molybdovanadophosphoric acid h4pmo11vo40 catalysts were prepared in alcohol by impregnation and the carbon deposition over these catalysts during the n-hexanol oxidation reaction was studied. the coke predominantly deposited on the catalyst surface in the form of ch., and it was not found that it caused the deactivation of the catalyst. the xrd, ir, xps characterizations reveal that the keggin structure of the cpmv was unaffected by carbon deposition. moreover, it was shown that the supported cpmvs over the mgo surface can be beneficial to eliminate the coke. the temperature programmed oxidation (tpo) study showed that coke was formed over the catalyst on two different sites: (1) deposited on the cpmvs which can be burn off at a low temperature; (2) deposited on the mgo which could only be removed at higher temperature. the coke content reached constant with the reaction time increasing. |
